OWA and Attachments

[philyboy]

Hi,

I have a E2K box setup as a front-end server with no stores etc. Users within the domain can logon to this for OWA and logon fine and also easily open attachments within messages. I have basic authentication setup with the domain set. We also have shops that connect to us via ISDN to access OWA. The workstations are not members of our domain and are standalone, and when they try to open the attachments they are prompted for username and password again. They have to type in domain\username and password, and try this about two to three times before it will alow them to open the attachment.

Any ideas anyone. OWA 2K seems to be much slower that 5.5, even though it is supposed to be quicker.

Thanks

Phil

What all configuration did you change to do this?

Is Basic the only one checked? Dan

What do you mean what all configuration?

Basic authentication is the only one checked. The same thing happens when I access OWA via the Exchange server itself. I just dont understand that it lets them log into their mailbox OK, but want further authentication in a different form when opening up attachments. And that does not always work. I could understand it if they were opening a differnet virtual directory or something.

Any help would be greatly appreciated.

Thanks!

Just another bit of information. It is not down to permissions either. If I access OWA from the shop PC under my account, it does the same thing in my mailbox. And I am a Domain and Exchange Admin.

THanks!!!

Any Anti-Virus on the box?

What if you access OWA on the back-end? Does it fail too? Front-End only proxies it back so just want to see.

Both the Front-End and Back-End are setup to only Basic? On at least exchange and public? Dan

Hello,

No the same thing happens wether they access the front end or back end OWA. They have an older version of IE (V5.0) but this should be OK according to the manuals. I will try and play with the clients versions etc, but with 150 shops over ISDN, this is not easy even with landesk etc.

Do you know of any ways to improve the performance of OWA. It is noticibly slower since upgrading on the front end and back-end.

Thanks!

If the back-end is slow it is the problem.

Front-End is just a proxy. Is Outlook slow on the Back-End? What is the CPU usage on the back-end? Dan

Hi DAn,

No, Outlook clients are not noticably slow on the back end. The CPU usage is fine. It just seems that when I had the 5.5 version of OWA (seperate server)running with the E2K back end, this was not slow. After I upgraded the front-end, it is now slower.

Do you know the main useful performance monitor counters to monitor for Exchange 2K, for IS, disk CPU and mem usage?

Thanks.

Phil.

I mean try OWA against the back-end.

If this is slow the front-end is going to be as slow.
