All -\n\nWe using the command 'adprep /forestprep' to update our WIndows 2003 R2 (Rev\n31) schema to WIndows 2008 (rev. 44), we are getting the following error:\n\nERROR: Waiting for ldifde to complete failed: 6\n\nHowever, the result of the command stated the forestprep was successful. We\nwent ahead and attempted to perform a domain prep but were unsuccessful. When\nwe investigated closer, we found the forestprep was failing when attempting\nto import sch32.ldf. When we performed the import of that file manually we\nreceived the following error:\n\nEntry DN: CN=Top,CN=Schema,CN=Configuration,DC=dev,DC=corp,DC=dom\nAdd error on line 217: Unwilling To Perform\n\nThe server side error is "An attempt is made to modify the base schema."\n\nAn error has occurred in the program\n\n\nAny suggestions?
