Hi,

We have about 30 or so clients connected to an W2003 server domain. the
computers are not top-notch but should be more than enough to handle simple
office work. The client computers are mostly Dell Dimensions 4600 2.8GHz
512Mb RAM.

Login is very slow, sometimes it takes as long as 40 seconds to log in -
sometimes even more than a minute. In general everything feels slow and
unresponsive. If I login on the computers local profile it takes about 5
seconds to login and the computer performs at twice the speed.

I would like to know why connecting your computer to a windows domain so
drastically changes a computers performance? I would like to know what part
of a computer takes the most impact upon connecting it to a windows domain
(harddrive, memory, cpu... etc) and why this happends.

All our client computers are connected to the server with very fast gigabyte
NIC's, and transfering large files from clients to computer is amazingly fast
- still, general performance is horrible.

Norton Antivirus is also an insane system resource hog and completely
disables the computer to be efficiently used for the 20-30 minutes it takes
to scan (which is does twice a week). If my employers would let me, Id switch
it for working AV software in the blink of an eye. :P

Thanks in advance.

I have 100 MHz computers that logon in 5 seconds. There are many factors
(number of clients logging in at once, load on DC's, roaming profiles, virus
scan at startup), but I would suspect problems with DNS. Troubleshoot DNS
and fix errors.

I had a client have this issue once. I discovered that they had been using
this little Linksys Router for all of their dhcp and dns, while still
logging into their domain. I placed the dhcp and dns roles on the DC
server, disabled them from the router and Viola! super quick login speed.
Definatley check your dhcp and dns setup.
