Hi there, Since I've installed ISA2000 on the SBS2003 server, my clients cannot connect to their internal shares across a VPN when out of the office. I've run the connection wizard from SBS2003 and selected to enable VPN connections, so there is no problem with the initial connection, but when they try to get to their shares via ip or unc name, they get an error message that the server/computer could not be found.
I've read numerous postings about this, but no-one seems to have given an answer to this as yet. Does anyone have an idea of how to resolve this? I'm about to uninstall ISA and revert back to RRAS :(
Is PING to the Internal Network from the VPN clients succesful? Did you check to see if they get the DNS, WINS information? Did you check ipconfig to see if the y get teh IP Address range that you set up from RRAS? Let us know and Good luck
Assuming everything is correctly configured from RRAS (it should be, because it was working b4), you need to check the Packet Filters Propeties from ISA.
Open ISA MMC Expand Firewall_Name\Access Policicy Right click IP Packet Filters and select Properties On the General Tab: All three options should be selected (the important here is Enable IP Routing) On Packet Filters Tab: All three should be selected On Intrussion detection Tab: All six should be selected On PPTP Tab: Allow PPTP traffic through ISA Firewall - VERY IMPORTANT for VPN All the intrsussion detection and packet filter stuff are for your protection, you don't want to enable PPTP and IP Routing w/o enabling your filters
