hay dude

not sure how you run your network with pc's conected if there all part of a the same build or there all personal laptops ect ect

i run a network of about 300 users and 200 pc all built the same way with the same restrictions ect ect

if your ghosting the machines the SID ID will saty the same Use Ghost walker or any other program that will change the SID ID

Or weather your network is bigger than you can control and people putting jack (personal) machines on your network that there not ment to ect ect

tip dude use TCP/IP get rid netbios( it a hassle more than it can help)

hope i can help mate

yea

i use clone technology for deploing my OS, but it's my first time that get this error, i use sysprep before making master image.

i check clients IP and Suffix .

all clients get 2 suffix with same suffix name,

- one suffix is desnigated by itself. ( when join clinet to AD )

- other suffix is applyed by DHCP server.

i delete record 015 (domain name)

i think that, DHCP suffix cause problem. when computer get new IP address or check DHCP get the same suffix as it got befor from DC, and it cause client windows think that other computer has this name.

any idea :-/

Try changing your computer name (Right-Click My Computer --> Properties --> Computer Name tab) and reboot.

open up dns and view all the records and verify no 2 records have the same name,

see if that helps

Also, if you are using WINS or it is enabled check the WINS database and make sure there are not two records for different computers that have the same name.

To clear the Netbios registrations (WINS) on the computer, go to a cmd prompt and type nbtstat -rr, hit Enter.

To clear DNS, type ipconfig /flushdns, Enter, then ipconfig /registerdns, Enter.

Good luck
