Shared Printer and folders from Win 7 to XP Pro not working

[Guest InfiniteMonkeys]

I manage a Windows 2008 R2 SBS network with a single server and a number of

 

new Windows 7 workstations. A couple of older XP workstations have been

 

upgraded to Pro and joined to the network. Recently, I replaced one of the

 

legacy PCs with a new Windows 7 Home Premium PC then upgraded it to Win7

 

Professional (HP5). I shared parallel printers from HP5 and all the other

 

new Win7 workstations can see the printers and access them. The XP station

 

(XP-PC) cannot. It can ping HP5 by name, but not view or access any

 

resources. This occurs even if I am logged in as domain administrator on

 

that PC.

 

 

 

Initially, I found there was an issue with SBS 2003 and XP SP2 and

 

firewalls, so upgraded the XP station to SP3 and numerous follow-up patches.

 

I also upgraded HP5 to all current patches.

 

When that did not work, I also went into gpmc and disabled internal firewall

 

with no effect. I'm not sure that worked, however, since the workstations

 

still showed the firewall managed by the server, but my administrator

 

override on workstations was still not allowed.

 

 

 

I suspect it is a problem properly accessing rights on the network, but have

 

tried all methods of providing rights to the computer and user to no effect.

 

 

 

I need advice on how best to proceed.

 

What are the next best tests?

 

What can I do to confirm it is not an internal firewall issue?

 

What can I do to determine or fix an OS problem on XP-PC.

 

What can I do to determine the effective share priveleges to a user on a PC?

 

 

 

Thanks
