SMB automount problems

I am new to this forum, so please ignore any naive mistake I am going to make. I have successfully integrate the AD and OD for my office. The Windows server system is win2003 and MAC server is 10.3.9. I can login a mac (10.3.9) with a managed user authenticated by AD. Two problems: 1. I did set the profile folder to //server/home/username in AD user property. At the first time I login, I can see the HOME folder is automounted, and is shown on the desktop and the dock. Then, if logout, and login again, the home folder will no longer be automounted, but I can use "Command+K" to mount it. No matter how many times I do logout-and-login-again, or restart the computer, the home folder cannot be automounted. The funnest thing is that, if I turn off the computer and have a good night. The next morning I boot up that computer and login with the same user, the home folder can be automounted again!!!! But if I logout and login again, no go. This scene happens everyday! What do you think is the problem? I check the system.log. The fist time I login, there is no error message, but the logins after that one shows the following err message: /System/Library/CoreServices/SecurityAgent.app/Contents/MacOS/SecurityAgent: MCXSecurityAgent: Skipping mount of kDSStdRecordTypeUsers/kDSNAttrOriginalHomeDirectory as "abcdef": Missing or badly formed URL. So is the win server's problem or the ad plugin's? 2. This one might be not a problem. But I just want to make sure. When the hoem is successfully automounted, the HOME icon on desktop links to the //server/Home, but not //server/Home/username/. Is it possible to let it link to user's own folder instead of the share point? Thanks a lot. You help sure helps me!
