Hi We have a COM+ component named CreateLetterRequest which is being called from another server. We installed it on two servers as a part of load balancing our application. It was working fine till date. Now one of the servers having some problem in the com+ component. The other one is working perfect. The error I am getting is : I got this error when i use a test application (windows application) . See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.IO.FileNotFoundException: The system cannot find the file specified.

I think the error is nothing to do with code as it in one server it is running. Can anybody help me to resolve this issue...? Thanks in advance.

Hi,

Thanks for ur valuable information. Actually when I check the log of loaded assemblies , i found out that the COM + dll is loaded from GAC. I think that COM+ dll should not be installed in GAC. When i uninstalled it from GAC , it works fine.

Thanks a lot
