ISA 2004 Server and Windows Time - 12.Aug.2008 3:21:12 PM

I have been struggling to get the following issue fixed ...

Currently, I have two ISA 2004 Servers in a DMZ. Both ISA 2004 Servers are configured as Reverse Proxies (Single NIC Interface) and are NOT members of an Active Directory domain (standalone Workgroup servers). Also, both ISA Servers are configured with Web Published Rules to allow access to our Outlook Web Access Front-end Servers.

The issue is that both ISA 2004 Servers report the wrong time. As a result, I'm trying to set up Windows Time on both ISA 2004 Servers to communicate with our Active Directory Domain Controller (PDC emulator role) on our enterprise network through a firewall. I cannot get the time synced up.

I have confirmed our firewall allows 123/UDP traffic to pass through both ways. I've tried editing the System Policy under the Firewall Policy to allow NTP or 123 traffic to pass through the ISA Server.

Does anyone have any suggestions how to get this working correctly?

Thank you in advance.

Make them domain members and the time will sync without doing anything. They will also be more secure in general.

1. Export the ISA Config to a file
2. Uninstall ISA
3. Join machine to the Domain
4. Reinstall ISA
5. Import the save Configuration

Other option, script it and run under task manager to update from the PDU/NTP server.

Hi guy,

Ohio? Heck, I've been through Ohio enough over the years I've probably drove past your house a few times and didn't know it.
