I used HFCHECK Hotfix Check Script 1.00 from MS to check patches on all W2K IIS 5.0 servers. Some of the ES servers running Datacenter on them and I got the patch from the Vendor. But when I run the utility on them it doesn't show the latest patch applied on them. Is it because the patch is from OEM. Well I thought atleast it should recognize it as its the same OS from MS. Secondly the patch is not for NT4.0 OS so how do you check on these servers. Thanks.
