Unexpected behavior

[bao]

Hi,

My system is RH7.2, kernel 2.4.7-10, samba 2.2.1a-4. Here is the problem
I'm encountering.

Samba has been running well for almost half a year. Everyone has an
account on the Linux box, and uses windows 98 clients. The password on
samba and windows are the same. When someone logs on in windows, his/her
password for windows will be used to authentication in samba. The shared
drives are mapped at startup.

Sometimes, we are reported that the network is busy, and the drives are
not mapped.
I have recently put in a more detailed log level (7 or so), and got this
log when this error happens.

There are two error messages, happened on the same logon.

1.

2. This message is in the middle of the log.

Could someone please tell me what I should do ??

Thanks in advance,
