Hi all.

On a dev.-XP.-box with all SP and updates, VS03, SQL etc. I should check a
solution I changed 6 weeks ago. The solution contains Web-parts and that
specific part gave  by opening the .sln the error message:

Unable to open Web project 'Web1'. The file path c:\inetpub\wwwoort\Web1'
does not correspond to the URL http:// Localhost/Web1. The two needs to map
to the same server location. HTTP Error 404: Not found.

Each time I tried, after reboot etc, I got that message. I checked my other
20 .sln's and no one gave any problems.
Hm, I checked IIS and it's settings but all looked good (more than 10 years
of experience there)
Thereafter I remarked that http://Localhost and http://127.0.0.1 gave
different output under IE but the same with FireFox;  IE said: file not
found.
HOSTS is correct concerning localhost.

After hours of trial, I opened a new XP-adm-user and opened my .sln with the
Web-part : no problems. Cross-checks: nothing obvious wrong.

So I guess some part of that user-settings must be wrong - but where?

And my question to you is: ever seen anything like that and/or know about a
tools to fix that user??

MS has in feb. 06 published several articles (841296, 318884, ) so there
must be some bugs here, because it happened after the big XP-updates in
feb-06.

Thanks,
