HELP! Exchange Server Issues...suddenly asking users for passwords and cannot add new users.
Posted on 2012-08-31
Please help. I have a windows 2003 Exchange Server that suddenly started giving me errors and I can't figure it out. New users aren't being recognized and mailboxes are being recognized. Also today users who have been using Outlook with no issues on our network are suddenly being prompted for a network user name and password and their outlook says Offline. When putting the user name and password in nothing happens and cannot bring their Outlook online and in sync with the server.
Prior to this the Server has been running just fine for over a year with no issues
A couple of days ago I went to add a couple of new users w/ exchange mailboxes to the network using the mail server and when I go to configure their account in Outlook on their Windows XP workstation I'm suddenly getting prompted for a user name and password. When I put in their user name and password nothing happens.
When I go to OWA and sign them in I'm able to log in but only once. As soon as I log off and try to get back in again nothing happens. It just goes back to the OWA login screen and the user and password box is blank again.
When I go to add or change permissions on my primary server (Windows 2000 Server) it doesn't replicate the changes to the rest of the network. My wiring and network switches are working fine and I can ping all the servers and other computers but my changes aren't being replicated.
Just today I'm getting calls from everyone saying that the are getting prompted for their network user name and password when they open up MS Outlook. This is a new issue and I know it's related to the servers not replicating. The people calling me are users who have been using Outlook with my exchange server for a year with no issues. Can someone please help.
My set up is as follows
I have a MS Exchange Server 2003 w/ SP2 on Windows 2003 R2 as the exchange server which replaced an old windows 2000 Server that was running Windows 2000 exchange. The Windows 2000 server is still on the network and it's being used for a program called Print Boss but not exchange. It's still listed as a PDC.
I have another Windows 2000 Server. This Server was our first PDC server and still is our Primary Domain Controller. It' controlls our DNS, DHCP and File and Print Server.
I added another Windows 2003 R2 Server 6 months back and made it a domain controller also since my Windows 2000 Servers are aging and I'm slowly moving data to this server.
Everything was working great up into the last week or so when things just started acting funky.
Please let me know what other details you require to help me resolve this issue. Thanks in advance.
