I have used wsusoffline for a couple years now, but I am now seeing significantly longer scan times for "Listing IDs of missing updates..." than in the past. On WindowsXP Pro domain-joined systems, IE6, ANtivirus disabled, Dell Optiplex 390 (Core 2 Duo 2Ghz), with no change in installed software, I am seeing consistent scan times of 50 minutes to list the IDs of missing updates. Installation of the 36 or so that were missing took only 20 minutes. During this time, the CPU is pegged at 50% (full loading of one of the two cores). The only process using CPU is svchost.exe (ie antivirus is not the issue). Any ideas as to why this is taking so much longer? I confirmed that the version of windows update agent was 7.4.7600.226.
Even on a Core i5 Optiplex 990, the 4-core CPU pegs at 25%, and takes just about as long. Unfortunately, I am not allowed to post the logfiles from these systems, but I can look up information if there are suggestions of things to check in the wsusoffline.log and windowsupdate.log.
Do I need to downgrade the windows update agent? Thanks in advance for any suggestions. I'm interested to know if mine is an isolated case, or if everyone with WinXP is seeing similarly long scan times.
