Workstations showing "Offline" - SBS Essentials 2011

hi,

we have a small SBS Essentials 2011 network with a few workstations. all of the workstations were connected using the Windows Connector software.

there are a couple of workstations that show up under the Dashboard as "Offline", when in fact, they are very much Online. I can even reach them using Remote Web Access.

thoughts? their "Offline" status disables backups, etc.

This is often caused by DNS problems or hyperactive firewalls - there's a troubleshooting guide that usually lives here but that seems to be down today, so try the archive.org version of that page.
Try pinging the clients by name and IP from the command line to see if their names can be resolved and they are accessible over the network. If they used to work and now don't, re-running the connect script often fixes this and won't change any other settings.

I should add that the first step would be to check the System event log (open the start menu and type "event viewer", open the "Event Viewer" and expand Windows Logs --> System. Then look for errors with source "DistributedCOM" and see if they match your non-connected client computers.

Hi,

so you're saying that uninstalling the Windows Connector software and re-installing may be the quick fix?

I've not seen it myself, but a user here who was having similar problems reported that it resolved the issue for him, and it's easy enough that it should be worth a try.

okay - I thought of that, but I'm always hesitant about uninstalling/reinstalling, as I'm leery about cluttering up the registry, etc.

but i'll give it a whirl.

Glad that worked for you Go-Bruins - can you confirm that just reinstalling the Windows Connector fixed it for you, just for future reference?
Regarding uninstalling and reinstalling: Products from decent software companies, and particularly those from microsoft, are usually very good at tidying up after themselves - it's much less of an issue than it used to be.

Well, it looks like uninstalling and reinstalling did not do the trick.

As a matter of fact, putting new computers on the domain seems to work, but again, they show up as offline...
