Hi all, been lurking in the shadows for some time, now to get off my backside and join the action. I have a number of Win XP Pro based computers that can be set running boinc, but they are networked with the internet connection via M$ ISA server 2000. Both PCs and server are fully patched. I cannot get boinc to run. The client starts but the attach to project routine fails with messages that it cannot connect. All PCs have access to the internet, and I'm running boinc with full admin rights. The problem must be with ISA server, but I can't see how to get round that. I was able to run seti@home classic using setiqueue on the server with the PCs connecting to the setiqueue. No setiqueue equivalent doesn't help here. I've looked at the proxy settings in the boinc client, and that don't work either. The PCs all I have admin rights to the entire network so within reason (it's an office) I can make changes, provided the business don't fall over. Any one got any ideas please?
