use adsutil to set you IUSR password manualy using the following command and try once.<br />
cscript.exe adsutil.vbs set w3svc/anonymoususerpass &quot;password&quot;<br />

I tried using the command you suggested. It seems to set the password, but I don't know that I was having trouble with that. I can set the password in IIS and in Local Users and Groups.<br />

I am getting 401.1 errors on my site. Running IIS 6, anonymous access only. I have changed the password on the IUSR account and and in IIS, I've also tried setting IIS to use my admin account. All to no avail. Directory permissions have been checked and double checked. The site was working fine two days ago and I have made no changes. I haven't even logged on to the server in days. I've restarted all appropriate services and the server itself. All five websites that it hosts are doing the same thing.

IIS 6 getting 401.1 errors

I am getting 401.1 errors on my site. Running IIS 6, anonymous access only. I have changed the password on the IUSR account and and in IIS, I&amp;#39;ve also tried setting IIS to use my admin account. All to no avail.

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.
