Missing ASP.NET tabs

Hi Group

Running a 64bit Windows 2003 R2 and in the IIS 6.in the default website I
don't have any ASP.net tab !

I've executed the command to enable 32 bit apps on 64bit box

also done the /aspnet_regiis -i (both 1.1. + 2.0) command - that
didn't change anything.

anyone knows this issue and how to resolve it ?

Thanks for any feedback
