We are using Cisco Security Agent 126.96.36.199. We have 491 clients, mostly Win XP.
We have noticed that within 3 days of CSA installation on a PC, WMI quits working. If you try to connect to a PC using wmimgmt.msc, you get the message: "Failed to connect to (PC name) because <Null>: No such interface supported.
If we reset Windows security using the command: "secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose" The problem is fixed, at least temporarily.
About 45-50% of our PCs are affected.
This is a big deal for us because we use SMS for automated patching and inventory of PCs, and SMS relies heavily on WMI.
The only fix seems to be to remove CSA. Putting the host in Test Mode, or turning off security don't seem to make a difference.
Nothing that we see in the MC event log seems to be connected to the problem.
Has anyone else seen this?
