Windows XP IIS 5.1 MetaBase corrupted somehow, reinstalling doesn't help

Somehow my MetaBase.bin is corrupted on my Windows XP machine. I've attempted to uninstall and reinstall IIS numerous times. I did see the Reinstalling IIS on WinXP machine post here which I made sure to follow exactly however after uninstalling IIS the Inetserv folder does not get completely removed it is left with.

MetaBase.bin aqadmin.dll aqueue.dll seos.dll

Anytime I delete those files they immediately reappear.

When I attempt to reinstall IIS I am presented with:

iis6.log

And in the event viewer

Event ID: 7023 The IIS Admin service terminated with the following error: The data is invalid.

Event ID: 10010 The server {A9E69610-B80D-11D0-B9B9-00A0C922E750} did not register with DCOM within the required timeout.

Looks like the problem occurred when trying to write the Cryptographic information in the Metabase i.e. iis_core:WriteSDtoMetaBase:Start. I suggest you uninstall IIS. Rename the MachineKeys i.e. machinekeys those are starting with c23 and 7a4. Then try reinstalling IIS.

Hope this helps.
