offline folders: random disconnects and errors from server

Hi all, got a very irritating problem:

There are 20 workstations connected to a win2k server and a sbs2000 server, both at SP4 with all patches.... the clients are all win2k pro and xp pro

There are offline folders set up on the clients, which are on both the win2kserver and the sbs2000 server.

Randomly, about 6 times per day, but not at the same time, the clients will be disconnected from the sbs2000 server with the offline folders error message "you are no longer connected to serverX - you can continue working normally, for details click on icon"

This ONLY happens to the offline folders on sbs2000 server. When it happens, the files in those offline folders are not visable at all. While this is going on, the user can still use the files off the win2k server, use email and browse the internet.

After about 5 to 20 minutes, the problem fixes itself and the offline folders on sbs2000 goes back online.

The domain controller is the sbs2000: there are NO errors in the event viewer of this server. However there are some errors in the event viewer section of the client workstations:

Windows cannot obtain the domain controller name for your computer network. (The specified domain either does not exist or could not be contacted. ). Group Policy processing aborted.

I am really out of ideas here as to what could be causing these problems?

Hi jason_jm,
Open My Computer.
On the Tools menu, click Folder Options.
Click the Offline Files tab, and then click Advanced.
Under When a network connection is lost, do one of the following:
To receive notification that the network connection has been lost and to continue working with offline files, click Notify me and begin working offline.
To make offline files and folders unavailable to you when you lose a network connection, click Never allow my computer to go offline.

Hiya Peter, those are already checked on all the laptops.... doesnt seem to help for some bizarre reason?

also, i made sure no invalid folders were being turned into offline folders by deleting the existing offline folders holding in ctrl-shift to wipe the cache clear, and then re-configuring offline folders....

oh hold on you saying i must choose one or the other?
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Any Joy?
jason_jmAuthor Commented:
well, its hard to fix this, because it only happens every few hours, so now I wait and see, changed the options in advanced settings, now the clock ticks I guess?

Pete LongTechnical ConsultantCommented:
