unable to find script library '/aspnet_client/system_web/1_1_4322/WebUIValidation.js

I have seen my problem about a hundred times. I Haven't found a solution that works for me.
I am moving my web site from an old server ms win2k3 no sp's. To a newer better one with win2k3 sp2
The path on the 2 machines is identical except the machine name.
From localhost I get "unable to find script library '/aspnet_client/system_web/1_1_4322/WebUIValidation.js'
From th www I get a logon dialog box everytime I attempt to do anything.
I have run 'aspnet_regiis -c'  no fix
Then I ran 'aspnet_regiis -i reinstalling and svr32 and reregistered the aspnet_isapi.dll  succesful.  
Web site still has the same errors.
I made sure my virtual directory was pointing to wwwroot, even repointed to 1_1_4322 still not working
I restarted IIS and or the machine between each  "fix"

Also I read Q 20762240  I don't understand how it helps

My users ad data to a sql database. Validation is server side. So "http://msdn2.microsoft.com/en-us/library/yb52a4x0(vs.71).aspx"  doesn't apply.

While I hate fixing things by reinstalling. Thats what I did. I removed application server from my server roles. Re-applied all ms updates. Reinstalled application server. Re built the virtual directory.  Took about 15 min.  Everything works. Been looking for a fix for two days.
Thanx all
