Debug of offline folders

Hi,

I've an ex-SBS2003 server (transitioned), where I use offline folders.

However, quite frequently, my client PC will take the shares offline

(whilst on a 100Mb LAN) saying the servers are not available.

Server CPU hovers at between 20-40%. memory is pretty much 100% anyway

thanks to Exchange.. No firewalls involved.

But I dont understand why my client thinks the server isnt there.

So - two questions:

1) Is there any debug I can enable on the client?

2) Network utilisation is <1%, ICMP roundtrip is 1ms, and with the

server stats above, what else could be causing it to "timeout"?

Would like to sort this as its quite annoying.

Thanks,

Adrian
