Windows services error 2003 DC

Hi Experts,

We have a network with a Server 2003 DC (soon to be upgraded!)
I am unable to start the above service "Lanmanserver Error 1059: Circular service dependency was specified."
 The only resolution at the moment is to reboot our Domain Controller...

I have checked the following reg path & can confirm that this is correct:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Rdbss Imagepath key - changed to system32\DRIVERS\rdbss.sys

Any advice please?

You don't actually specify which service(s) you are trying to start...

There seem to be a couple of potential solutions offered around though - first to run "sfc /scannow" (without the quotes) and the second is to change the service logon to local system (but without knowing which service...that may be detrimental).

Apologies the service we are having trouble starting is lanmanserver. Can you offer any other solutions besides an sfc scan?

We have attempted this & it hasn't resolved the issue.

Well the first thing I would look at is what services it is dependent upon and then check which services depend on it - it may be that you have the same ones listed in both cases.
The error seems to suggest that it is related to service dependencies being a circular reference.

Check the service dependency.

look for lanmanserver
within it there is a dependonService it may point to a service that in turn points to a service that inevitably points to lanmanserver as a dependency creating a loop.

The link to

confirms the path, but it is an older version and includes no information beyond for the description.
