Having to replace workgroup names

[xantia999]

I have an ongoing problems with two customers sites. Both are using XP Pro
and using Peer to Peer networking, they are also using "simple Files
Sharing". On a regulare basis the computers cannet see each other across the
network, "Unable to open files you may not be authorised", if I change the
workgroup on each machine than all is O.K. for a couple of weeks of so, what
am I doing wrong ??

More details please.

Do you mean the two customers sites have the PCs "linked" together on
a common "network?"

No they are separate systems, the problem I have is on both sites
