Tried installing SP2 on the problem box. The Server Properties window still appears for about a second then disappears.
Have registered the problem server on another SQL Server EM on the LAN that has straight up SQL 2000 no Service Pack. The properties window for the problem server still disappears, while properties window for the other server comes up just fine.
Checked via sp_configure what the settings would be on the box as compared to the other SQL Server box that does not have the problem. Both the problem box and the box without Service Pack have 4 processors. I didn't change any server properties on either box. They are new installations not in production yet. The only difference in the comparison of the sp_configure output between the two boxes is the affinity mask minimum value.
Would that cause a problem with the properties window?
Haven't yet called MS, but I suppose that's the next step.
