NAV Server (NST) crashes with message "The process cannot access the file '.

Mathes

Hi, sometimes the Windows Client can not longer connect to our NAV Server, the Service is still running but Connection is not possible, the Event log Shows the following error:

The process cannot access the file 'C:\ProgramData\Microsoft\Microsoft Dynamics NAV\70\Server\MicrosoftDynamicsNavServer$navrtc1\source\Query\Query50000.cs' because it is being used by another process

Does anyone have an idea what the reason for this error message is?

Regards

Did you did any modification in Service Tier like MaxConnections or something like this??
Did you tried restarting the service or creating a new one as if you did some modification and just forgot and just to cross check.
