Hi, I was running build 933, and in fact even though I upgraded to 1158 is still shows 933 as the build number. I upgraded because I thought it might fix my problem. I can check the image and it verifies Ok, but when I try to explore the image, it times out trying to assign the letter to partition 1of 1, the error message "Cannot assign a drive letter to a partition from the image archive". Small Business Server 2003 with SP1 installed, RAID 5 disk array. Any thoughts on what the issue is? Why does 933 show as the build and not 1158, is this a known bug? Thanks.
