 Posted: Thu May 18, 2006 1:49 am Post subject: Find users doesnt always give results - spotty AD query/sear |
 |
|
When I use the AD MMC and find users, it doesnt always give my results. It
will tell me no results found. If I try again later, it works just dandy.
Details:
Brand spankin new Dell Blade 1855, Xeon 3.4 Ghz and 1 GB of memory.
Installed Windows 2003 and did all updates.
Created new domain and imported 130,000 contact entries. These entries are
just the display name and email address only.
Every 15 minutes during office hours, we import another 5 contacts.
Over the first week I began to notice when I would search a contact, it
would say no results found. I would try again later and it would be found.
These were imported with the initial 130,000 contacts. After about a week,
the problem seemed to get worse and worse until we had to axe the project for
now.
There are no other AD servers/no replication. The machine appears to be
running quick and doesnt seem overloaded. No other software running on this
box.
Maybe I was wrong, but I thought AD could handle simple lookups for 130,000
contact entries? Are there tweaks that are required? |

130k contacts is small, nothing to really worry too much about. ADUC is a poor
tool to test things with because it hides most errors. Switch to a command line
tool like dsquery or my own adfind to do the queries and see what errors are
popping up. With only one GB of RAM I would guess your issues are either your
disk is being overloaded as your DIT probably (this is a guess) doesn't fit into
memory fully so the DC has to race across the disks and you could be timing out.
Also if I recall the query that ADUC generates for a contact kind of sucks, I
think they just use objectclass=contact which is inefficient.

Thanks Joe,
We will try upgrading the memory to see whats up. I know our downfall is we
didnt do any perf monitoring before hand. Thanks for the tip and I will let
you & everyone know what turns up.
