I have googled this and searched the ZA forums, but not found a solution, and feel this is a unique ZA problem.
I have an XP Pro PC (SP 2) and Vista Home Premium (SP1) Laptop. I have connected both computers to 'MSHOME' and I could connect to either PC's shared folders from the other, via my wireless router (a netgear wgr614v9 for those that care about these things). I then use my xbox to stream from either PC to my TV.
The XP machine was already running ZA - (ISS I think - firewall and antivirus with spam filter) and the laptop standard windows (defender, firewall etc) - both computers also running latest versions of 'Spybot - Search & Destroy/Teatimer' and 'Spyware Blaster' (just in case this is causing some sort of random conflict with new ZA ES!) running in the background.
Yesterday I installed the newest ZA 'Extreme Security' on both computers (a 3 license version) and set up the IP addresses (assigned using DCHP, but assigned a fixed IP through the router) of both computers to the trusted zone, on the other machine (if that makes sense!).
I put all of the ZA settings at the highest sensitivity, and have been blocking / allowing things on an ad-hoc basis (not ticking the 'always do this' option) just to make sure I dont accidentally restrict something important! (He said thinking that in actuality he probably has done this exact thing!)
Now, everything else is running perfectly (as far as I know) - including the XP PC can still connect to the shared folders on the Vista machine and the xbox, BUT for some reason the Vista Laptop won't connect to the XP PC. I can see the computer name, but everytime I click on it, it just hangs.
I am trying / have tried various combinations of windows firewalls on and off, zonealarms on or off and have got it to work with one of the computers running ZA, but not both... I seem to have blocked something (process, service, something..!) in ZA that is stopping the Vista machine connecting to the XP one... but which service/process, and on which machine?! (If this is indeed the problem...).
Happy to provide any further info, and will try and find links to other sites that I have followed trouble-shooting on to show what I have already done.
N.B. - I have done nothing else to either PC since I discovered the problem apart from enabling a few services and tinkering with firewall settings etc to try and get the machines talking.
The XP user has admin rights, but currently the Vista user profile I am using doesn't (I can change it if need be, but would rather not).
