Hopefully this is a variation on the previous svchost.exe troubleshooting questions.
We initially got reports of slow performance on a number of Windows 7 PCs. Resource Monitor showed that the IP Helper Service was consuming a large amount of CPU time. We disabled the IP Helper Service across the organisation using GP as we don't use any IpV6 transition services.
After disabling IP Helper we continued to receive problem calls. This time Resource Monitor showed that the BITS service was consuming a large amount of CPU time. We can't disable this but instead moved BITS to its own svchost.exe process.
After moving BITS we still continued to receive calls. The User Profile Service (profsvc) is now the culprit! Presumably if we disabled this or moved it to a separate process the problem would move to a different service.
Obviously this is baffling as the problem seems to move from service to service, all within the netsvcs svchost.exe group.
- Affected machines are Windows 7 SP1 32-bit. Latest Windows Updates installed.
- This problem occurs at random. It can occur during startup, at the logon screen or when the user is already logged on
- We've ran various malware scans (SCEP, MalwareBytes, RR) and found nothing.
Any troubleshooting strategies would be appreciated.
