/etc/passwd strange behaviour!

/etc/passwd strange behaviour!
Hi there,
first of all, here is my conf of a uname -a
Linux SAMBA 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i686 unknown
on a fedora machine.
Here is my problem: every once in a while, the line containing root disappears in the /etc/passwd, disabling all logging on my server. Any one have any ideas?
As you can see in the uname, it's a samba server!
Thanx
I just found out in the /var/log/messages:
Jun 2 14:50:03 SAMBA smbd[1607]: [2005/06/02 14:50:03, 0] rpc_client/cli_netlogon.c:cli_net_sam_logon_internal(406)
Jun 2 14:50:03 SAMBA smbd[1607]: cli_net_sam_logon_internal: NT_STATUS_NO_SUCH_USER
Jun 2 14:50:03 SAMBA smbd[1607]: [2005/06/02 14:50:03, 0] smbd/password.c:domain_client_validate(1572)
Jun 2 14:50:03 SAMBA smbd[1607]: domain_client_validate: unable to validate password for user ROOT in domain WORKGROUP to Domain controller atr_2. Error
was NT_STATUS_NO_SUCH_USER.
Jun 2 14:50:03 SAMBA userdel[1608]: delete user `root'
Jun 2 14:50:03 SAMBA userdel[1608]: delete `root' from shadow group `sirepa'
How can this be?

setarch
SETARCH(8) System Administration SETARCH(8) NAME
setarch - change reported architecture in new program environment and set personality flags SYNOPSIS
setarch <arch> [options] [program [arguments]] arch [options] [program [arguments]] DESCRIPTION
setarch This utility currently only affects the output of uname -m. For example, on an AMD64 system, running 'setarch i386 program' will cause 'program' to see i686 (or other relevant arch) instead of x86_64 as machine type. It also allows to set various personality options. The default program is /bin/sh. OPTIONS
-v, --verbose Be verbose. -h, --help Display help (it is also displayed when setarch takes no arguments). -V, --version Output version information and exit. --uname-2.6 Causes the program to see a kernel version number beginning with 2.6. -3, --3gb Specifies that processes should use a maximum of 3GB of address space on systems where it is supported (ADDR_LIMIT_3GB). --4gb Ignored (for backward compatibility only). --list List architectures that can be set. -B, --32bit Turns on ADDR_LIMIT_32BIT. -F, --fdpic-funcptrs Userspace function pointers point to descriptors (turns on FDPIC_FUNCPTRS). -I, --short-inode Turns on SHORT_INODE. -L, --addr-compat-layout Changes the way virtual memory is allocated (turns on the ADDR_COMPAT_LAYOUT). -R, --addr-no-randomize Disables randomization of the virtual address space (turns on ADDR_NO_RANDOMIZE). -S, --whole-seconds Turns on WHOLE_SECONDS. -T, --sticky-timeouts Turns on STICKY_TIMEOUTS. -X, --read-implies-exec Turns on READ_IMPLIES_EXEC. -Z, --mmap-page-zero Turns on MMAP_PAGE_ZERO. EXAMPLES
setarch ppc32 rpmbuild --target=ppc --rebuild foo.src.rpm setarch ppc32 -v -vL3 rpmbuild --target=ppc --rebuild bar.src.rpm setarch ppc32 --32bit rpmbuild --target=ppc --rebuild foo.src.rpm AUTHOR
