Trouble connecting Vista Ult SP1 & XP SP3

[LesterDent]

I have been playing musical OSs on a new video server I'm putting together - tried XP MCE and found it didn't like my Intel 8-ports Sata RAID board (but it networked just fine, thank you!). Changed over to Vista Ultimate SP1. Hardware works fine, and media sharing with extenders works fine over network, but I cannot get my main XP Pro SP3 machine to recognize.

WIndows firewall turned off. Norton IS 2009 installed on both machines, with the comps set as Trusted.

Part of the problem may be that when I first set up the network on the Vista machine I went with the default WORKGROUP. I caught it later, and changed to the ever-popular MSHOME I use on the other PCs. Network (set for Private on the Vista PC) now shows as MSHOME. But when I try to look at the shared drives (individually set to ALL under sharing permissions for Everyone) from the XP PC I see that PC under MSHOME and the Vista PC still under WORKGROUP.

I've looked under the nethood in D&S but cannot see any reference to WORKGROUP. I tried to delete the network setup but it is always greyed out. Disabled the NIC & tried to delete, no joy (and yes, I remembered to enable the NIC afterwards...).

I really, really don't want to reinstall Vista to start over (since the bloody thing takes a good day to sort out all of the updates) and start off with MSHOME, but I need to get these comps talking to each other.

How can I delete a network setup to re-do from scratch? Barring that, is there a Registry value I can clear on the XP machine so it won't look for the Vista PC there any longer? I suppose I'll search the Registry when I finish and find the problem (isn't that the way it works after you bleg?) but think there should be some better way to handle this.

TIA.

Uninstall Norton COMPLETELY and use this Norton Removal Tool to finish the job. Then see if you still have the problem.
