After installing ISA 2004 on a Win 2003 domain controller, it worked fine, but when I retsarted the XP workstations, no user could log in including the administrator, how can fix this problem?

well does the domain controller have 2 NICs? If not you must uninstall ISA 2004. install a second NIC which will serve as your WAN link. Reinstall ISA 2004 and specify the seond NIC you installed at the WAN link which ISA is to protect.

note: you must log on locally to the Domain Controller to gain access. will not be able to log on to the network with any device in a 1 NIC instance because ISA Server is protecting that NIC [firewalled]. ISA server blocks all traffic after it's installed until it's configured to allow traffic for whatever services you wish to publish.

There are 2 NICs, and they are configured correctly, I have no problem with ISA itself, all I am asking for is the log on problem

you will need to install the ISA client on the worksations for authentication remember you internet is going out through a proxy now.

if ISA Server was installed correctly and the configuration wizards run correctly, there should be no reason the domain administrator, the local machine administrator, or users workstations could not log on to the domain. Further, domain administrator should be able to log on at the DC.

If you have no access at all to the DC, both from a workstation and at the DC itself, there really is no way to get on the machine unless you use an administrator password reset program or you reinstall the O/S.

ISA should not be installed on a domain controller [unless you are using the Small Business Server addition of Windows which is designed to have ISA server running on it].
