Q: I do not know if I do something wrong, but I have this strange problem. I am installed Active Directory, so I can manage user accounts on the domain without local accounts on computer. Okay, that went well. Now, when I try and access a share and transfer files, my speed is reduced by about half. When I disable Active Directory, I get full speed again, but Active Directory is reduced. BTW, the client is Windows XP Pro, and I made a domain member, when I ran the first test, and removed it when I disabled Active Directory. Does anyone know what could be wrong?
Best Answer: Hello.
have you installed service pack 1 on windows 2003 server ? and which version have you installed
there's
Server Edition
Enterprise edition
Web Edition
here's the SP1 Download link :

NOTE : you might need to reinstall network on Windows 2003 server .
Good Luck
Re:here's a better idea, for testing purposes how about you setup a ramdisk so you can have a little better test bed.

Re:I highly reccomend leaving it disabled unless this machine has a very good UPS that is configured to shut down the box in the event of a power failure. The last thing you need is the directory database corrupted from an abnormal shutdown i/expressions/rolleye.gif

Re:I forgot about write caching. I don't know if this would cause your times to double though. I could see it having some slow down though. You can still enable Write caching if you want on the IDE controller. They disable it because you can corrupt the AD database if you suddenly lose power.
You would need a second physical disk to enable it if you don't want it enabled on your system drive. The setting is per disk, not partition.
Re:No, it is the same HDD. I have an 80 GB WD drive, in one partition. I have the OS installed, and was copying to and from that drive. I didnt't know that Write-caching was disabled. Is there any way to re-enable it (without messing up Active Directory)?, and if not, if I partition the disk, will the second partition have write caching enabled?, or do I need a second physical drive to be able to have full speed transfers?
Re:Originally posted by: guy
When you install ActiveDirectory it disables WriteCache on the System Drive, are you copying files to/from the system drive on the Domain Controller?
Although if you remove the DC role I wouldnt think that it would re-enable write-caching, not that I can say I've ever stopped to look.
I guess the more important question, are you copying files on the DC from the same physical drive that the OS is on (system drive), or is this a seperate physical drive?

Re:Yes, both computers are members of the domain (I'm transferring files between a workstation and the server). The way I am saying 50 mbps is because #1) It takes twice as long to transfer, and #2) Under network usage in the task manager, it says 40-50 % usage, when before it said 95-100%.
Re:and are both computers you are sharing files between members of the domain (and listed there)?
Also, how have you determined that it is "speeds close to 50Mbps"? Are you running some kind of benchmark software or are you just saying "it takes twice as long to xfur files"?
The biggest reason that you've had to keep bumping this is because you havent clearly paraphrased your problem and havent clearly stated your questions, that's why (I'm guessing) many people have skipped over this thread and not replied and why those who have replied have not easily been able to answer your question.

Re:I can see the other computers in the domain, but the problem still persists. When I attempt to use filehsaring, it is at speeds closer to 50 mbps rather than the full 100 mbps. Before Active Directoy, I had full 100 mbps.

Yes, they joined the domain. I see the machines under Active Directory. What do you mean by "and Computers MMC console"? I know what the MMC console is, but how do I view other computers in it. Thanks again for helping.
On the Server (or a box on the domain with the adminpak installed):
Administrative Tools>Active Directory Users and Computers
Expand the Domain, expand computers
What he is looking for is right there.

I don't know if this id your problem. But at work they hard this hella-problem with filesharing, the transfers were slow and after a while they just started crapping out. It turned out to be two things. The major problem was a misconfigured dhcp server. The rarp was all screwed up so the server was having a hard time keeping the connections going because it was having a hard time keeping track of the clients on the ethernet network. (remember that in a ethernet network computers are kept track of by their mac addresses, tcp/ip rides on top of that. If the ip address can't be resolved into a mac address you are not going to be able to find the computer. Of course if the ip address is not part of the local network you computer with send the request to the gateway's ip/mac address — usually a router or switch– and let that device take care of resolving the ip address.) But that is probably not your problem. Check and make sure that all your nic cards are set to run at 100Mb if that is what your running. Remember if you are running a older ethernet card, like a old 3com, they say they support 100Mb but realy it's a different protocol then the modern 100Mb versions and everything will default back to 10Mb. Thats why I run 10 megs at home right now.
The two NIC's are modern NIC's. Less than 8 months old.

Re:Thanks for your help so far, but I think you misunderstood me. All the clients are able to resolve the Active Directory server just fine (I have flushed all DNS cache on the local machines before attempting a lookup). The only problem I have is that filesharing is about half the normal speed. As far as I can tell, the DNS is fine, and all clients are successfully resolving the server by NetBIOS and by IP.
Re:Just because the wizard setup DNS doesn't mean it was done correctly. You need a good knowledge of how to setup DNS and how DNS works to setup AD. Basically if your machine is having trouble finding the server (because it can't locate it via DNS) it's gonna be a slow transfer.
I suggest that you read up about AD before you play around with it. AD is not for the faint of heart. It's a very complicated and powerful directory services. If you've only got a handful of machines connected to a server I suggest you stick to a workgroup with local user accounts.
If you want to get into AD I suggest you read the whitepapers on MS site. It's got the best information you can find on the Internet.

Are you sure you configured DNS correctly? This is a common problem and can cause what you are describing. What do you mean by disable AD? You can't just disable it after it has been installed.
I allowed Active Directory to setup and configure the DNS. How can a misconfigured DNS affect the filesharing? The way I disabled it was to completely remove the Domain Controller role from the server. If you know of a setting I can change to make the DNS and filesharing work how they should, what would that be? (I am new to Active Directory, as you might tell).
