Network Auto-Disconnect

Windows has a network auto-disconnect function that will do an OSI Layer 1 disconnect after 15min, to save power presumably. This can cause problems with certain applications, namely Outlook in some cases - that will start doing some strange things and will return to normal only after restarting the program.

A solution is to disable this feature by running the following in an administrator cmd session.

net config server /autodisconnect:-1


To make it permanent we need to edit the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters
There should be a dword named "autodisconnect"
Set the value to 0xFFFFFFFF

Trend WFBS v7.0

The latest version of Trend has a couple of issues, namely it no longer supports Windows 2000 (This could be an issue if your site is still 2000 based) and the client agent does not upgrade properly on SBS 2003 servers.

After running the upgrade - the client agent is not installed properly and is not running on the server.

First make sure the latest critical patch is applied:

Next we need to remove all traces of the client agent from the server using the removal tool:
ftp://transfer:data@techsupport.trendmicro-europe.com/WFBS/7.0/SA%20uninstall%20-%207.0.1343.zip

Now we should be able to install the latest client on the server without any further problems using the "\\Servername\ofcscan\autopcc.exe" method.

PrintUI DLL - Automatically configure printer settings

You can use the printui.dll method to add/remove printers from users profiles quietly like this:

To add a printer run:
rundll32 printui.dll,PrintUIEntry /in /q /n "\\Servername\Printer Share"

and to remove an existing one run:
rundll32 printui.dll,PrintUIEntry /dn /q /n "\\Servername\Printer Share"

These can be added to logon scripts, etc.

N-Computing Troubleshooting II

Ensure that Windows Updates are disabled on the vSpace server.
Found that KB981957 (Windows 7 x86) caused the vSpace server to malfunction and terminals cannot connect. You should be able to uninstall this update and restart the server to get it going again.

N-Computing Troubleshooting

Running N-Computing 5 x L-130 terminals using a Windows 7 (32bit) PC as a server using vSpace 5.1.3.12. The system has Trend WFBS client agent installed and is a part of an SBS 2008 domain and has some end-user applications installed.

System appears to stop functioning every few month due to Trend or Windows updates that seem to break the system. This is due to the fact that the system is probably not fully Windows compatible or certified and appears that certain Windows updates overwrites critical files and settings.

Here are a few tips I have gathered while troubleshooting and resolving problems with this system:

1. Do not DISABLE the windows firewall. You can turn it off or configure exceptions that will allow the terminals to connect to the server without restriction -
This will prevent the vSpace services from starting properly. It is also a good idea to allocate static IP addresses to the terminals.

2. Ensure EVERYONE is assigned the "Allow log on through Remote Desktop Services" right. This is accessed through the gpedit.msc and is a local Computer Policy.

3. Configure Anti-Virus exceptions for the vSpace services and executables. Otherwise the services won't start.

4. Make sure the logon settings for the vSpace services are set to "Local System account" and check the "Allow service to interact with desktop" is checked.

Support for N-Computing can be difficult to obtain but you can start with making sure you have the latest version of the vSpace server.
