Outlook Web Access Problem

[coop1984]

Hello our OWA has stopped working on our server (Exchange 2003). We get the error:

HTTP/1.1 503 Service Unavailable

Can anybody help?

Thanks

A few things to check - sorry if you have already done some of these.

Preform a IISRESET on the server
Are you all you services started?
Restart all your Exchange services
Restart you server.
Are you publishing it through ISA2006?

[coop1984]

Hello yes I have tried all the below, and it is not published through ISA 2006.

Ive had this problem, our backups had failed and the server started filling up with temp files. No free disk space knocked off OWA. Check your C:!

[coop1984]

Plenty of space on C.

it could have something to do with the site application - what error messages do you get in the event log?

A few other questions and things to check.

Even though your 'Exchange Information Store' has started - are the databases mounted in Exhange management console?

What service pack are you on for exchange 2003?

How big is your database?

I occasionally got this on 2003, another reason why i moved to 2007. Check your Microsoft Information Store has started correctly.. If it dont start, your schema server doesnt work. Also, check in system manager... locate the mailboxs and make sure they have been mounted.

@coop - Do you use BackupExec by any chance?

[coop1984]

Yes we do

[Ryan]

Then try this:

Start > Run net stop rxWriterSvc

then

net start rxWriterSvc


We have an issue with BackupExec chewing up memory and forces IIS and a few other services to throw a hissy fit. Lemme know if this sorts it.

[coop1984]

Unrecognised command.

Problem still exists

Have a look at this

@coop - did you manage to check my last list - let me know the information and I'll see what I can come up with.

An error we keep getting is

Initialization of external interface OLEDB failed; Error ecServerOOM.

All databases are mounted

Its R2 SP 2.
