marcvalk — Wed, 05 Sep 2007 09:00:40 +0000

Configure Firewall Client application settings

To configure Firewall Client application settings

In the console tree of ISA Server Management, click General.
where?
- Microsoft ISA Server 2004
- Server_Name
- Configuration
- General
In the details pane, click Define Firewall Client Application Settings.
On the Application Settings tab, click New.
In Application, select an application or type a new application name.
In Key, type the name of a key.
In Value, type the value to set for the key.

Notes

To open ISA Server Management, click Start, point to All Programs, point to Microsoft ISA Server, and then click ISA Server Management.
To remove an existing application setting, select it from Settings and click Delete.
To modify an existing application setting, select it from Settings and click Edit.

The following table lists the entries that you can include when configuring the Firewall Client software application settings. The first column lists the keys that can be included in the configuration files. The second column describes the values to which the keys can be set. Note that some settings can be configured only on the Firewall Client computer; you cannot configure them using ISA Server Management.

Entry	Description
Disable	Possible values: 0 or 1. When the value is set to 1, the Firewall Client application is disabled for the specific client application.
Autodetection	(Can be set only on the Firewall Client computer.) Possible values: 0 or 1. When the value is set to 1, the Firewall Client application auatomaticlaly the ISA Server computer to which it should connect.
NameResolution	Possible values: L or R. By default, dotted decimal notation or Internet domain names are redirected to the ISA Server computer for name resolution and all other names are resolved on the local computer. When the value is set to R, all names are redirected to the ISA Server computer for resolution. When the value is set to L, all names are resolved on the local computer.
LocalBindTcpPorts	Specifies a Transmission Control Protocol (TCP) port, list, or range that is bound locally.
LocalBindUdpPorts	Specifies a User Datagram Protocol (UDP) port, list, or range that is bound locally.
RemoteBindTcpPorts	Specifies a TCP port, list, or range that is bound remotely.
RemoteBindUdpPorts	Specifies a UDP port, list, or range that is bound remotely.
ServerBindTcpPorts	Specifies a TCP port, list, or range for all ports that should accept more than one connection.
ProxyBindIp	Specifies an IP address or list that is used when binding with a corresponding port. Use this entry when multiple servers that use the same port need to bind to the same port on different IP addresses on the ISA Server computer. The syntax of the entry is: ProxyBindIp=[port]:[IP address], [port]:[IP address] The port numbers apply to both TCP and UDP ports.
KillOldSession	Possible values: 0 or 1. When the value is set to 1, it specifies that, if the ISA Server computer holds a session from an old instance of an application, that session is terminated before the application is granted a new session. This option is useful, for example, if an application crashed or did not close the socket on which it was listening. By closing the old session, ISA Server immediately discovers that the application was terminated and can release the port used by the old session immediately.
Persistent	Possible values: 0 or 1. When the value is set to 1, a specific server state can be maintained on the ISA Server computer if a service is stopped and restarted and if the server is not responding. The client sends a keep-alive message to the server periodically during an active session. If the server is not responding, the client tries to restore the state of the bound and listening sockets upon server restart.
ForceCredentials	(Can be set only on the Firewall Client computer.) Used when running a Windows service or server application as a Firewall client application. When the value is set to 1, it forces the use of alternate user authentication credentials that are stored locally on the computer that is running the service. The user credentials are stored on the client computer using the Credtool.exe application that is provided with the Firewall Client software. User credentials must reference a user account that can be authenticated by ISA Server, either local to ISA Server or in a domain trusted by ISA Server. The user account is normally set not to expire; otherwise, user credentials need to be renewed each time the account expires.
NameResolutionForLocalHost	Possible values are L (default), P, or E. Used to specify how the local (client) computer name is resolved, when the gethostbyname API is called. The LocalHost computer name is resolved by calling the Winsock API function gethostbyname() using the LocalHost string, an empty string, or a NULL string pointer. Winsock applications call gethostbyname(LocalHost) to find their local IP address and send it to an Internet server. When this option is set to L, gethostbyname() returns the IP addresses of the local host computer. When this option is set to P, gethostbyname() returns the IP addresses of the ISA Server computer. When this option is set to E, gethostbyname() returns only the external IP addresses of the ISA Server computer-those IP addresses that are not in the local address table.
ControlChannel	Possible Values: Wsp.udp (default) or Wsp.tcp. Specifies the type of the control-channel used.

Installing Vista Drivers on a Windows 2003 Printer Server

marcvalk — Wed, 05 Sep 2007 08:26:49 +0000

Windows 2003 isn’t Vista aware. So when you’re using a Windows 2003 Printer Server you might run into a problem with automatic installation of printer drivers when you’re auto-enrolling your printers (via Kixtart or so).

For publishing you’re Vista Printer drivers on a W2K3 machine follow the procedure described below.

needed: windows Vista Workstation, Admin account, Vista Driver (download from your suppliers website)

log into a Windows Vista Workstation with your admin account
(if you want to install x64 drivers, log into a Vista x64 version)
browse your printer server (\\)
Find the Printers Share and open it.
Right Click anywhere and select “Server Properties”
Select Tab “Drivers”
Click on “Add”
The “Add Printer Wizard” Appears
Click on “Next”
Select the type of driver you want
Click on “Next”
Click on “Have Disk”
Select the driver you downloaded and click on “Ok”
Click on “Next”
Click on “Finish”

UPDATE:
I am running Vista x64 now, and above didn’t work as it should.
You can also do this from your workstation, by starting Print Management (control panel :: administrative tools). There is only one catch… make sure that the your printer is listed, just as it shows on the share. i.e. My vista machine says it’s a HP Laserjet 2100 PCL 6, but my server use the driver: HP Laserjet 2100 Series PCL 6.

ISA Firewall Client settings

marcvalk — Tue, 04 Sep 2007 13:06:00 +0000

example: defining thunderbird.exe to use Microsoft ISA Firewall Client.

Start ISA Server Management
..open Microsoft Internet Secuurity and Acceleration Server 2004
..open
..open Configuration
..open General
..click on Define Firewall Client Settings
..select Tab Application Settings
Click on the New Button
in the text box next to Application add thunderbird.exe, select the Key LocalBindTCPPorts and add as value the ports you need (in my case 143,110,25) as a comma seperated list.

Click Ok twice and apply settings

DNS Warning: EventId 11167

marcvalk — Tue, 04 Sep 2007 09:46:11 +0000

I recently encountered the following EventID warning:

Event Type:   Warning
Event Source:   DnsApi
Event Category:   None
Event ID:   11167
Date:
Time:
User:       N/A
Computer:
Description:
The system failed to register host (A) resource records (RRs) for network adapter
with settings:

Adapter Name : {4FD62166-14A0-49F4-9714-213D474F8FA9}
Host Name :
Primary Domain Suffix :
DNS server list :
Sent update to server :
IP Address(es) :

The reason the system could not register these RRs during the update request was because of a system problem. You can manually retry DNS registration of the network adapter and its settings by typing “ipconfig /registerdns” at the command prompt. If problems still persist, contact your DNS server or network systems administrator. For specific error code, see the record data displayed below.

I found a lot of posting regarding Microsoft Firewall, but the solution is very simpel:

Check your DNS Server > there was a CNAME entry (could be any other) in my DNS domain preventing the client to update its own record.
Just remove the entry and execute ipconfig /registerdns. Within a minute the client should appear correctly in DNS and the warning should not reappear.

FF Extension: Web Developer must have

Joomla – date layout stays English

marcvalk — Fri, 24 Aug 2007 07:45:54 +0000

Since a few days I started to irritate myself because of the following line in a website (joomla website) I was developping (www.dimdy.nl):
laatst geupdate op (wednesday 08 august 2007). This site language was set to dutch, and the country layout to nl_NL. This used to work on other sites.

After trying different settings this one finally worked for me nl_NL.ISO8859-1.
If you got the same problem, try one of these settings:

nl_NL
nl_NL@euro
nl_NL.iso88591
nl_NL.iso885915@euro
nl_NL.ISO8859-1
nl_NL.ISO8859-15
nl_NL.utf8
nl_NL.utf8@euro

FF extension: Gmail Manager

marcvalk — Mon, 06 Aug 2007 13:23:23 +0000

If you got a gmail account and you use Firefox (who doesn’t!!), you should install the GMail manager extension (created by Todd Long).

It allows you to manage multiple Gmail accounts and receive new mail notifications. Displays your account details including unread messages, saved drafts, spam messages, labels with new mail, space used, and new mail…

Foxit Reader

marcvalk — Mon, 06 Aug 2007 07:47:08 +0000

An alternative to the “heavy” Adobe Acrobat Reader.
The leightweight foxit reader, downloadable here.

It is free to use, the download is only 1,67 Megabyte “small” and it’s lightning fast.
So get rid of the acrobat reader and install foxit reader
