I have an exchange 2007 server, sp1, running on Windows Server 2008. I have a combination of Outlook 2007 and 2003 clients, all connecting via https over rpc (outlook anywhere). It's been running for a while now, no hiccups, everything is golden.
Today, the remote outlook 2003 clients can't see the GAL unless they first log into the vpn, and then open outlook. 2007 clients are fine, local 2003 clients are fine, of course. It's only 2003 clients that can't view the GAL remotely unless they log into VPN. This wasn't the case yesterday, and remote 2007 clients are fine.
What in the world?
