Windows 2008 Updates Loses Connection

I have created two virtualised Windows 2008 servers using vmware player. One is a domain controller, the other has been successfully added to its domain. When originally installed, both had full web connectivity. They both installed a series of updates, including Service Pack 2.

However, they both have lost network connectivity. neither can ping the router. The domain controller has a fixed ip address. The other is on DHCP and is showing a 169 address. I doubt it's a problem with the hardware, as the host machine has had full connectivity to the router throughout.

What network mode do you have the VM's set to under settings? Maybe you need to select bridged mode again for both virtual machines?

Yes, they were both set to bridged originally.

I would check them and make sure that vmware tools are installed on both machines. Maybe deleting the NIC and re-adding it will fix the issue? I hope this is a testing environment...

The vmware tools were installed on both. At the risk of being completely thick, I wasn't sure if you meant removing the NIC from the vm settings, or removing it from device manager. But that didn't make any difference anyway. In the end I think the router may have been having some objection to the static ip for the AD controller (although it started out ok). So what I did was set it to DHCP and set the router to reserve the address. That works ok. And I can add/remove the second server from the domain ok.

I was referring to removing the NIC from the VM settings and re-adding it but I'm glad you found a solution!

That is strange that your static settings were causing the issue.
