Audio Driver for windows server 2003 sp2

[gxmcn]

hi,guys.
I have a problem while installing audio driver for windows 2k3 sp2
on my t23[2647].
first of all,I havn't installed the sp2,and there is no sound on sp1.
So after ugrading to sp2,i download all most all the driver i can get from the internet[the lenovo offical website(xp;nt;9x)] and some general Ac97 audio driver;But all of these driver cannot work on my laptop.
ps:I have used the compatible feature.
Finally,sorry for my awful English.^_^

Finally i found the solution.
run mmc.exe then add the sevice.msc and start the windows-audio
service.
yeah,i have made a silly mistake.
it is not the ibm t23 audio driver itself but the audio service casuing this problem.
ha,ha^_^
