This solution is …

?Windows 2008 Server x64
Please make this folder.

C:\Windows\SysWOW64\config\systemprofile\Desktop

?Windows 2008 Server x86

Please make this folder.

C:\Windows\System32\config\systemprofile\Desktop

…instead of dcomcnfg.exe.

This operation took away office automation problems in my system.

A Desktop folder seems to be necessary in the systemprofile folder to open file by Excel.

It disappears from Windows2008, Windows2003 had the folder,
and I think it cause this error.

win2008,win2003 There will be this problem .
That is to say C:\Windows\System32\config\systemprofile and C:\Windows\SysWOW64\config\systemprofile Create a directory named Desktop Directory can solve the problem .

So far, the problem has been solved perfectly .
