I have a problem using the mount -t ... command with Linux.

My configuration is as follows:
- Computer1 (IP:192.168.1.53) is member of a Windows Domain with Intranet and Internet access running Windows XP (SPs are not relevant to my problem).
- Computer2 (IP:192.168.1.54) is only a workgroup computer with Intranet and Internet access.
- Computer3 (IP:192.168.1.55) running Suse Linux 9.1 Professional incl. the lastest Samba Release 3.06 I found today.

- Computer1 has a share xxx with access for Everyone.
- Computer2 has a share xxx with access for Everyone.
- Computer23 (Linux) has two directories /mnt/comp1 and /mnt/comp2, both created with root and accessrights 755.

PROBLEM using the mount command
1.)
- mount -t smbfs -o username=Administrator,password=zzz //192.168.1.54/xxx /mnt/comp2
- everything is OK and I have rw access to this share.
2.)
- mount -t smbfs -o username=Administrator,password=zzz //192.168.1.53/xxx /mnt/comp1
- nothing works. the share dissapear as well in Konqueror as also in my console with dir. In console I can cd /comp1 - but, with dir I get access denied.

In Konqueror I can use

smb://192.168.1.53/xxx --> get a password dialog --> get rw access
smb://192.168.1.54/xxx --> get a password dialog --> get rw access

- umount to the shares is possible and successful.

Has somebody a idea where I loose "Accessrights" while mounting to Computer1?

Thank's for your help
