process test

Sometimes (on one particular server) the process test fails.
When I reboot that server, the problem is solved.

During the fail of that test, there is no reply.
At the same time, other tests on the same server have no problem at all !(services, diskspace, folder checks, ...)
When I edit that test, and click the drop-down for the process-list, I get the message "warning, cannot retrieve process list from \\server"

The problem (at that time) is the same when I start HM on another machine. (win2000 or server2003)
When I try to connect with a different user, the problem remains.
Restarting HM (or machine) isn't a solution.

PS: When I use pulist.exe (ms resource kit) or performance counter test via HM I can see the processes of that remote server.

Any suggestions ? (better than rebooting that server ?)

HM version: 4.42

Gert

H'm....
What if you restart Remote Registry Service on that server? Does it help?

The testing server is NT4 and has no "remote registry" service.

???
In this case test should not work at all. In order to retrieve information about processes HostMonitor connects to remote pseudo-registry...
Are you sure?

PS I know NT 4 does not have this service installed by default but it is included into Resource Kit.

I'm sure "remote registry" service isn't available on my NT4 server(s).
I checked other servers where I check processes too with HM without any problem, and I don't see that service ...

I'll send you an export my serviceslist of a working server ...

I tried to find some information on microsoft.com but...

Windows Me/98/95: To use RegConnectRegistry, you must install the Microsoft Remote Registry service. If you don't do this, calls to RegConnectRegistry return ERROR_DLL_INIT_FAILED. Perform the following steps to install the Microsoft Remote Registry service.
================
Windows XP Home Edition: You cannot use this function to connect to a remote computer running Windows XP Home Edition. This function does work with the name of the local computer even if it is running Windows XP Home Edition because this bypasses the authentication layer.
================
and so on...

I cannot find mention about Windows NT 4.0. Probably I was wrong. Looks like Windows NT 4.0 can provide read-only access to registry without this service, Remote Registry service is necessary to provide write acess to the registry.
I could assume underlying service (RPC service) is reason of this error. If this service fails, Process test method will not work. But this service is too important, you will experience other problems if RPC service fails. E.g. Performance Counter and Service test methods will not work either. But they work. I don't know what can produce such problem
