I am no longer able to log into my Exchange 2013 SP1 ECP site. Here are a few items to consider:
- Installed replacement UC on 5/7/14. Configured services POP, IMAP, SMTP, IIS. Removed IIS from existing UC which still had 6 days of life. Both certs identical. I did no further changes for this new cert other than install it through ECP.
- "Old" cert died 5/13/14 @ 8a. New cert took over without any problems.
- Continued to use ECP through close of business 5/14/14. Late on 5/14/14 I attempted to log into ECP remotely thru a VPN to migrate users from our Exch 2007 server. Could not access ECP.
- When I attempt to access ECP, I enter <domain>\<username> and password. When I hit "enter" or "sign in", the page flashes and the password field is empty.
- I am still able to log into OWA
- I cannot log into ECP using the server name, localhost or cert name.
- Currently using default settings of FBA and Basic authentication
- UC is correctly bound to both front and backend of IIS (443, 444)
- Everything else is working correctly for the Exchange site. I have been continuing my migrations through Powershell. I just can't log into ECP.
- I created a new Exchange Admin user only to find I still could not log into ECP.
Short Version: I was able to login and then, after a four hour stretch, I was not able to login. No errors on the web page or Event logs. Exchange is routing mail correctly.
I have scoured the web for that past couple of days looking for a solution but the issues I find are throwing up a web page with an error of some sort. Since I'm not experiencing that issue, I'm a bit stumped. I'm no expert, but I'm not a novice. Since 2013 is a new rebuild, I thought it best to ask for a little assistance. Any advice/assistance would be appreciated.
