I thought this might be useful. So I recently had an issue where my system got somewhat royally messed up and a main part of that was the .NET Framework. Well, even after reinstalling and following several "fixes" online, it wouldn't reset the ASPNET Machine Account. I've also seen many other posts where people couldn't restore the ASPNET Machine Account. So after further investigation, here's what I did:To restore the ASPNET Machine Account in Windows XP:Part 1:Start > Run > %systemroot%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe /iNote: change the version number accordinglyPart 2:Start > Run > regedit > OKNavigate to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > ASP.NET > MachineAccountsSet ASPNET to (0)If you do not see MachineAccounts, Right-click on ASP.NET and select New > KeySet the new key to MachineAccountsWithin the MachineAccounts key right-click > New > DWORD Value > ASPNET and set it to (0).Part 3:Start > Run > control userpasswords2 > OKSelect the Advanced tab > click Advanced buttonGo into the Users folderDouble-click ASPNET account and UNcheck "Account is disabled"Go to Member Of tab and click AddType in Users then click OK and OK again to save and close the ASPNET account.Part 4:Restart computerYou now have the ASPNET Machine Account actively back on your system.This is something I had to find out myself by viewing information on another system along with some very small and hard to find bits and pieces of information gathered from the internet. I hope this helps whoever has trouble with restoring the ASPNET Machine Account!Please repost this at will so that it can be shared everywhere as needed, but remember to give credit where credit is due!
