I have a SBS 2000 Server SP4 running IIS 5 and ISA SP1 w/Exchange 2000 SP 3. I have rebuilt this a number of times, mot recently because all of a sudden the icons and other graphics such as buttons in OWA have disappeared and are replaced with code or blue boxes with red X's in them.
I have rebuilt this server several times as it is really a test lab. It has worked fine before, this is a fresh install with no modifications to IIS or ISA. ISA does have the feature pack installed, but it did when it worked before. I recently rebuilt this server becuse of just this problem. I completely reformatted all drives when I rebuilt the server. So it is a clean install with all service packs and security patches.
I have tried accessing OWA externally and insternally with different versions of IE. I have tried accessing it from the server as the Admin, same issues. At one point I thought it was McAfee GroupShield, but during the last rebuild I tested it before installing GroupShield. I am not running SSL yet.
I am really at a loss on this one, as a long time fellow EE member any suggestions or help would be appreciated. Extra points if you want them.
