I have a Windows 2008 standard server which acts mainly as a file server and VPN server using Routing and Remote Access. The server is plugged directly into their RV082 Linksys Router. The server is an IBM System x 3200.

For the past couple of the months the server's network freezes randomly. After it freezes nobody can access the shared folders or connect to the VPN. The only way to fix it seems to be rebooting the server. The network only seems to freeze when people connect to the server using VPN connections.

I have tried updating the server's network drivers and the firmware. I also tried disabling and restarting the Routing & Remote Access service with no luck.

Does anyone know what's going on?

UPDATE:

I just connected to the server using VPN, then used TightVNC to connect to one of their workstations... after 15 seconds the server's network connection froze.

VPN seems to work fine for file and print sharing. Once you connect using VNC through the VPN the network freezes. What is going on?

Have you checked the event logs at lockup times?

Are you getting any NIC errors in the event logs or anything? Have you thought about trying an add in NIC and seeing if the problem ocurrs?

Also alot of this seems to be nic related have you verified all the NIC settings and configurations? E.G. your not loading any extra protocols you don't need, your IPCONFIGS and all that look great?
