SolidWroks SolidNetWork License Manager and Windows Small Business Server 2003

My Solidworks SolidNetWork License Manager software is installed on a Windows Small Business Server V2003. Recently, the IT company that manages our systems updated SBS 2003 with a service pack. Since that happened, people have been getting randomly disconnected from the server. Normally it is only for a few seconds to a minute, but several times it has been half an hour or more. The IT support company sent a tech who changed some settings and it stopped, but then the license manager wouldn't find the dongle to load a new license file. Thursday I updated the license manager and installed a new license file. I am now running FlexLM 15/4. The random disconnect problem is back. The software finds the dongle just fine, but now people get disconnected.

Does anyone have any experience with this problem or know what might cause it? The IT support company just wants to move the license server to another PC and see if that solves it. The problem is that it worked for 18 months without a problem and I can't find anything online with regard to the problem.

Thanks.

We are running a Server2003 setup and are not seeing this. Here is what I would do first:

There are log files for the network license server. Have a good look. If you can't make sense, let your VAR interpret them.

Look at the log files on the server. When something goes wrong it will many times show up there. There are application logs and security logs. Look at both places. Cherries are bad. Don't just look for things with flexlm, look for network things too.
Look at the Active directory logs and the dns logs too.

I would say it is unlikely that the license server itself is in trouble. You should also look at the config files for the license server. Depending on how many licenses you have and how critical some projects are you can always have those few borrow a license for a day.
