Hi Guys, I have an issue, which goes thus:
I have 4 boxes running Windows Server 2003:
Server 1 - An HP ML 370 G4 Server Running Windows Server 2003 wt SP2. Its my primary domain controller (is also hosts WSUS and McAffee ePO)
Server 2 - An HP ML370 G4 Server Running Windows Server 2003 wt SP2. Its a File and Application Server
Server 3 - An HP ML350 G4 Server Running Windows Server 2003 wt SP2. It hosts Exhange Server 2003 and its a Secondary Domain controller (with global catalag enabled - same as Server 1)
Server 4 - ISA Server 2006 Running Windows Server 2003 wt SP2
For several reasons, Server 4 was initially just a regular HP Desktop machine but yesterday, after close of work, I had changed it to an HP ML370 G5 Server. I ran Security Configuration wizard to harden the server and also ran all updates for Windows Server 2003 and ISA server 2006. I did the basic config to enable HTTP access for my clients. I tested on a few clients (Web Proxy - IE) and it worked fine before I closed. I also have GFI Web Monitor installed on the same machine.
This morning, everything was working ok when I arrived at the office, so I got down to define more restrictive access rules in accordance with the company's Internet access policy - restriction is either by IP or Active Directory Users/User Groups.
I defined the first rule Ok, but when I started trying to added users and groups to the second rule, I got an error: Cannot Determine User/Computer name. Rpc server is unavailable.
At this point I also observed that the usernames were no longer being listed in the Isa Log.
Subsequent, I also noticed that Server 1's AD User and Computer MMC won't respond. I restarted Server 1. When it came back up, the AD User and Computer MMC was Ok but it takes about 2min before the MMC will launch when clicked! Please see attached file for some of the Event Logs for Server 1 and 3
DOES ANYONE HAVE AN IDEA WHAT JUST WENT WRONG AND HOW TO RESOLVE IT?!!!
