Fileserver (networked hard disc) in "internet zone" - can't change???

I have 2 networked hard discs acting as fileservers in my local intranet (which consists of 2 studio computers - Mac and PC, an office PC running Vista, and the 2 networked drives, all under the same Workgroup)...

I have no access issues on any of my machines except the office PC running Vista (Home Premium 64)... on the Vista machine, even though I've added the IP addresses of the networked drives to my trusted zone, they show up in Windows Explorer as being in the "Internet Zone" and I can't seem to change that (which creates all kinds of rights/permission issues for some of the applications I'm running)...

Any ideas?

Bueller?

Really? No one???

\\fileservername

Will this work?

Thanks for the reply - I've tried every possible variation of IP, servername, full path, I could think of... no difference!
