Service Control Manager error in event viewer

Running a Windows Server 2003 SBS, this server runs AD, DHCP, DNS, File & Print, Exchange

Recently I have been receiving a two different Service control Manager errors in event viewer. The first error is:

Event ID: 7038
Source: Service Control Manager
The WinHttpAutoProxySvc service was unable to log on as NT AUTHORITY\LocalService with the currently configured password due to the following error:
Cannot start a new logon session with an ID that is already in use.

After receiving this error I changed the logon account for the service to Local System account (because I do not know the password for the Network Service account) and now am receiving this error:

Event ID: 7000
Source: Service Control Manager
The WinHTTP Web Proxy Auto-Discovery Service service failed to start due to the following error:
The account specified for this service is different from the account specified for other services running in the same process.

Now I could go to the other services and change them to Local System account but those services include the DHCP and I am not willing to mess around with that until I am sure that changing that logon will not affect DHCP leases.

I have done an initial search on Google and and have not found a solution as of yet.

Has anyone come accross anything like this before and if so what was the solution you found?

have you tried a reboot?

Sounds like the process has to run as Localservice and that it has crashed but still has an open handle...

WinHttpAutoProxySvc service runs as a NT Authority\LocalService account. This account does not have a password, so any password information that you provide is ignored.

IPv6 had been disabled on the server.  I re-enabled it and the issue was solved.
