Hi

I have a Windows Server 2003 R2 x64 file server. When I deploy SEP 12.1.1101.401 (RU1 MP1) to this server and reboot it afterwards,¨the server BSODs with a error in tcpip.sys. After disconnecting all NICs from the network, the server boots up correctly. If SEP is removed, the server works correctly. The whole scenario is reproducable.

An analysis of the minidump shows that the symtdi.sys driver creates a DRIVER_IRQL_NOT_LESS_OR_EQUAL error. I've attached the analysis to this post.

On the same server, Backup Exec 2010 R3 is installed. Removing the NIC drivers and reinstalling them didn't help.

Can anyone out there help me to resolve this issue??

Kind regards from switzerland;
