Unable to change Service parameters remotely

Hey all, I'm trying to change a bunch of snmp parameters remotely and not having any luck. I can go into Computer Management, right-click and connect to the remote computer and open up the service but when I try to change something I get the following error:

Code:

Failed to read a Registry key. This may be due to lack of resources. Try closing other Windows applications to fix the problem.

Even when both computers don't have anything running I can't get in. I've tried logging into my computer as the Domain Administrator but I still get the same error. I can access my 2k12 servers and a few remaining XP machines but none of my Windows 7 computers. Any ideas? Suggestions? Recommendations?

Thanks,

Joe B

I'll even take any guesses for something that might help. It's just snmp for now but who knows what else may pop up down the road.

Thanks,

Joe B
