I have a strange problem which I am currently unable to fix - hopefully someone can help.
There are about 5 client PCs connecting to a 6 month old Dell Poweredge Windows Server 2008 server. Some are pretty old and running XP, they have no problems. There are two new Dell Vostro Windows 7 PCs that both experience the same problem, but not necessarily at the same time.
They lose access to the file shares on the server for around 1 minute, it then comes back by itself. The shares go offline and they cannot access anything that isn't cached on the local PC.
This has been going on for a while and I've yet to find an answer. I've used one PC as a guinea pig for fixes and nothng has worked - I've tried disabling all the advanced 'features' of the intergrated Broadcom network card on the PC (flow control, WOL etc), turning off RDC and installing a DLink PCI NIC which I've just found has also not fixed the problem.
I can't find anything to help this on the internet so I'm hoping someone has seen this before.
Thanks in advance,
