Yep, nailed that one! It must be VMWare because I had the same issue with VMWare installed. Goodbye to VMWare it is then!! At least on this server ;)


I the have same problem after I install vmware server. After I switch to vmware workstation 6 beta 3, this problem still exist. Damn!


So, have you found a way to fix it after removing VMWare server?
My webmaster and I would like to be able to see the tab again, but...it's still not showing up even after uninstalling vmware server AND running aspnet_regiis -i again (from the .net 2.0 directory)

Yeah, it appears that VMware is doing something very nasty to the registry - so I doubt that you'll be able to get the tab back.

I guess someone should 'raise hell' with the folks at VMWare to let them know about this (though they probably already know about it).


A gent I work with figured out how to fix the issue where the APS.Net tab disappears from IIS Manager. I know this will work on 32 bit systems. I’m not sure how it will affect 64 bit Windows IIS installs… are they even broken… anyone care to check/try?

1) Stop the IIS Admin service (and any services that depend on it)
2) Open C:\WINDOWS\system32\inetsrv\MetaBase.xml in notepad. _DELETE_ the line that reads ‘Enable32BitAppOnWin64=”TRUE”’
3) Start -> Run -> iisreset

Your tab should now be back and functional.

If not - sorry, but it may help some people.


Mike C,
I was just reading your post over on the original thread, and it looks like you had already seen this fix. Sorry to appear to steal your idea there.
In our case, it's a good solution since the missing tab is on a 32-bit install of W2K3 server...

I love Microsoft, honest, Dave

You d man!

This worked brilliantly after I installed VMware on a 32bit win2003 server.

Thank you!



This does indeed work:

1) Stop the IIS Admin service (and any services that depend on it)
2) Open C:\WINDOWS\system32\inetsrv\MetaBase.xml in notepad. _DELETE_ the line that reads ‘Enable32BitAppOnWin64=”TRUE”’
3) Start -> Run -> iisreset

I, too have VMWare installed. I ran the steps above and the tab has re-appeared. You rock!



Damn, You saved my day! Its working...

Can I just say... YOU GUYS ROCK!!! I'm running VMWare and had the same problem. The simple .XML edit has made me a happy man.

Thanks a ton!

Rex Winn


This also worked for me. Thank you!


I've been trying to work out exactly when my tab went missing - and you guys are heros! Yep VMWare. The cure worked for me too. W2K3 Standard 32bit.

Big thanks


Thank you so much!

Lars, Sweden

Worked for me too! Windows 2003 with VmWare Server 1.04

You rock my world... I thought I had lost dot net and the end was nigh... But alas, you saved my but!

Thanks... :)


I have the same problem too but on a different OS and IIS versions. Anyone have a fix for Win2k with IIS 5?




You Guys rock. solved my problem.
