login script error

Scenario: We're migrating our users from NT to AD however
we still have alot of Win98 machines. In order to update
the client for MS networks registry setting on the users
desktops, I've put together a kixtart script which makes
the neccessary change to the registry. I've tested the
script by putting into the NT user accounts profile and
watch a test user authenticate, call the script, then the
window that says "Your windows logon script is running"
appears in the upper left hand corner. From there, the
DOS window comes up and runs the kix script which is part
of the .bat login script.

My problem is, that "Your Windows logon script is running"
message will not go away. After I wait a substantial
amount of time, I hit "Cancel", it goes away then I check
the registry and confirm everything worked great. The
domain is updated to point to the new AD domain. But I
HAVE TO GET THAT WINDOWS MESSAGE TO DISAPPEAR. My goal
would be for it to not even pop up because I'm afraid a
user might see it and hit "cancel" which would in turn
jeopardize the kixtart script from running.

Here is the output of the kixtest.bat file which is going
to be placed into the user NT account profile. From
there, I'll paste the Changereg.kix test script. What am
I doing wrong?

kixtest.bat

net use K: \\pdcservername\netlogon
K:
copy K*.dll c:\windows
kix32.exe Regchange.kix
net use /d /yes K:
exit

output of regchange.kix

if @producttype "windows 98"

writevalue
("hkey_local_machine\system\currentcontrolset\serv ices\msnp
32
\networkprovider", "authenticatingagent", "addomainname", "
reg_sz")

writevalue
("hkey_local_machine\system\currentcontrolset\serv ices\vxd\
vnetsup", "workgroup", "addomainname", "reg_sz")
endif
exit

Again, my whole issue is getting that Window to dissappear.

Thanks!
