Users Cannot Access My Site

[mjm917]

Recently, my organization upgraded to MOSS SP1. The upgrade went smoothly and I thought all was well. Until... after a few days -- I don't know why -- users started receiving login prompts when trying to access their My Site by clicking the My Site link (

http://<server>:<port>/_layouts/MySite.aspx).

After trying to login 3 times they get a 401 error -- IIS logs show a 401.1 followed by 401.5. Searching the internet for a solution, the closest I could come to the issues was the following:

----------
Our MY Sites are hosted at

http://sharepointfarm/my

and somehow all permissions were removed from that site collection except for our farm admin.

Once we gave the proper read access to "nt authority\all authenticated users" on that site collection, everything went back to normal. We are not sure how it happened
ether and of course, no said " oh yea, I did that".

I have looked through Central Admin and do not see where or how I can do this. Any help on resolving this issue would be greatly appreciated?

BTW, users are still able to access their My Site if they access it directly using a URL like

http://<server>:<port>/personal/<username>/

I have also verified the Personalization Services Permissions for "NT AUTHORITY\Authenticated Users"
+ Manage Analytics
+ Personal Features
+ Personal Site

I am starting to think that the issue might have to do with NTFS permissions in the 12 hive. I have confirmed that the identity specified in the app pools also has permissions to the physical folders/files. I granted MODIFY permissions to the group that "nt authority\all authenticated users" was a member of. No Dice.

What would the consequences be if I ran the SP config wizard again?

All -

Turns out, the problem was not related so much to SP1 as it was to a recent DB migration -- SQL 2k to SQL 2k5. The DB migration was performed prior to the SP1 upgrade and was uneventful or so I thought. Turns out that when restoring the backup during the migration, the parent My Site collection was not restored was was restore improperly. It has since been restored and all is well with the idividual My Sites. Thanks for your help.
