I have been experiencing connectivity issues with a DC on my student network, in effort to resolve it, I read about NetDiag a tool from Sever 2003 install disk. I read that it will work on Server 2008 system, so I ran it. Attached is the report given, in it you will see that DNS test failed. I tried searching the web for an answer but could not find any thing related to 2008 server. On this server I also have an extra nic connected to a Dell Powervault storage array. Not sure if this is related, but when I go into the network configuration on the nic connected to the network, when I close it I get the following message.
"Warning - Multiple default gateways are intended to provide redundancy to a singe network (such as an intranet or the Internet). They will not function properly when the gateways are on two separate, disjoint networks (such as one on your intranet and one on the Internet). Do you want to save this configuration?"
Have had this message before in 2003 server, also did not have a Powervault.
Not sure where to look, at this point, over all the system seems to run okay, except (another issue related to DNS) when trying to validate trusts between Staff and Student network, system reports that cannot find logon server. There is a lot going on, I think and hope it is wrapped into the DNS issue. Suggestions are greatly appreciated.
