Well everything is on the same network and IP range, and I can ping every machine from any other machine - but, when I added a couple of workstations' IPs to the host file on the server it worked! So it looks like unless I can find another way round it I've got to add ALL the workstations into the server's host file, and make sure any new machines also get added! What a bore - but it least it works. Thanks for your help, kshah58!

Hi, I'm also having firewall problems with a fresh install of SOLUS 3.9. I have opened up ports and done everything else as instructed, both by the Capita pdf and the suggestions on this forum. I have triple-checked my GPO. The same GPO is sent to the server and the workstations. gpresult /r shows that the GPO has been applied to the server under Computer section but - the agents will not install unless I drop the server's firewall. The workstations firewalls are up and work fine. The messages in SOLUS 3 usually read: Install Active - Checking Operating System, Copying Agent Files, The Remote Machine Cannot Be Contacted. Any thoughts? Philip
