I've recently installed Microsoft ISA Server on the server where the LanSweeper installation resides.

Since then I'm not able to update the info of my client PCs (mainly Win 2000, XP and some Vista).

The error tab shows:
Wmierror - RPC unavailable. (Exception HRESULT: 0x800706BA) PC1 (xxx.xxx.xxx.xxx).

I've created some rules on ISA Server for traffic on ports 9524, 1139 and 2843, but the error isn't gone yet.

I need to know if I missed some ports or, better, if someone can instruct me a good configuration for ISA.

Thanks in advance.

I cannot recommend this setup.

There could be a lot of things wrong with your setup yo give a good answer to your question.

Could you, at least, indicate me the right ports and protocols that I must enable on ISA server ?
Thanks.

For isa to your workstations : open all outbound ports because WMI uses dynamic ports
Form your workstation to isa : open port 9524

Thanks for your help and your feedback. Now I can communicate.
I suppose that installing LanSweeper on an ISA Server computer is not a Best Practice.
