We are having a problem with one of our SQL servers, and in comparing it to the backup server which is working fine, I noticed some differences. I attempted to correct the differences, but no luck.
The dell server has 4 dual-core processors and at one point hyper-threading was enabled. One of our DBAs recommended that it be turned off. We didn't have any major problems until recently and it seems that getting this setting right is the lynchpin. Any suggestions?
