In the server application events log I get a .net runtime 2.0 error. This is the error.

Faulting application explorer.exe, version 6.0.3790.3959, stamp 45d6a1b7, faulting module nalshell.dll, version 10.0.1.0, stamp 46f14b2f, debug? 0, fault address 0x00024eb8.

The nalshell.dll is 10.0.1 on a 10.0.3 server??

Any Ideas?
Thanks
