Login Prompt after ~3min timeout

I have a report which I am running from a web front end, which, when exported
to excel with certain parameters, takes several minutes to run. After
something between 2.5mins and 3mins this will prompt for a username and
password. Providing a valid username and passoword gives you another 3mins
before you get prompted again and so on until you have been prompted 3 times,
after which you get an IIS permission denied message up.
Running a SQL Server trace against the server makes it appear as if the
report restarts running as the stored procedure is re-run (even though this
had completed successfully before the timeout was hit), so the report appears
to start again.
Looking at the Logfiles there are message about orphaned requests and Item
with session ... not found in database.
I have tried increasing the:
Database query timeout to 240 secs - no effect.
The report timeout to unlimited - no effect.
MaxMemoryLimit to 80% - no effect.
ASP timeout to 600 sec - no effect.
I can't see any error messages in the event log.
Does anybody have any idea what is actually timing out, and even where I can
set it.
Please through in random suggestions, I am willing to try anything. BTW
this is happening on both the server which is running SP2 and the one with no
service packs on.
Many thanksI should have added:
It is nothing to do with permissions as this is fine with a smaller dataset,
also I am administrator on, one of the machines on which this problem is
occuring.
Session timeout values are default of 20mins.

This was set to 2mins.
