Publishing Visual SourceSafe 2005 on Internet

If you have readed tons of Manuals, Forums, Tutorials about how to setup Visual SourceSafe 2005 over Internet as I was, and you are 100% sure that the settings used on your SourceSafe are correct and that everything should work just fine, but it doesn't!
Here is one Tip that I was unable to find in any of the online documents:

In case you are having problems with Check in in your SourceSafe over HTTP from External Network (behind ISA 2000/2004) make sure if you have URLScan Security Tool installed and check out the urlscan.ini file for the [AllowVerbs] tag.

Under [AllowVerbs] you should have PUT method added in order to successfully Check In Files from Outside world.

At the and, your urlscan.ini file should contain the following lines:

UseAllowVerbs=1
..
..
..

[AllowVerbs]

;
; The verbs (aka HTTP methods) listed here are those commonly
; processed by a typical IIS server.
;
; Note that these entries are effective if "UseAllowVerbs=1"
; is set in the [Options] section above.
;

GET
HEAD
POST
PUT

Just in case, would be good to restart your Firewall Machine in order to be sure that the new settings are applied.
