URLSCAN blocking MS IM with exchange 2k

I have been trying to us Microsoft IM in house with our exchange2k server
and recently no users can authenticate to it...

I get an error in MSIM 2.2 and 5.0 that says:

Exchange Messaging Authentication Failure. The person logged onto this
computer does not have permission to use the specified e-mail address.
Please supply an email address and logon credentials for that address.

the W3SVC1 log shows:

2003-11-17 13:53:06 10.0.1.51 - 10.0.1.22 80 SUBSCRIBE
/instmsg/aliases/jqpublic 200 0 - -
2003-11-17 13:53:06 10.0.1.51 - 10.0.1.22 80 GET /<Rejected-By-UrlScan> 404
123 - -

the URLSCAN.ini has the appropriate allow verbs...
[AllowVerbs]

;
; Note that these entries are effective if "UseAllowVerbs=1"
; is set in the [Options] section above.
;

GET
HEAD
POST

SUBSCRIBE

so why am I getting shut down?

thanks in advance,

Hi Timur,

Based on my experience, I'd suggest you can configure the IIS UrlScan following the directoin of this KB article Q309508. Please go to:
309508 XCCC: IIS Lockdown and URLscan Configurations in an Exchange Environment
http://support.microsoft.com/?id=309508

Please feel free to let me know if you have any further questions.

Does this answer your question? Thank you for using Microsoft NewsGroup!
