Here is the situation. Client lost power two days ago battery backup kicked on, Primary domain controller stayed online, power restored 1 minute later. Since that time we have had connectivity issues to the server. PDC is handling file\print services and dns. What seems to be happening is the server has a delay when responding to connection or clients will lose network access for 10-15 mins. I am able to ping the outside the company but will receive timeout roughly 30 pings in then then after 5-10 timeout RQ I receive a response. Checked event log and DNS unable to find anything that would be causing this. Ran hardware diagnostics on all passed. Even switched the Primary NIC. Our exchange server which is on a separate box is running fine. Any ideas?
