newbie, connect with win98: called name not present

[ubub]

hi,
i´m trying to connect from knoppix to a win98 machine. some hours ago it worked but i can´t reconstruct what i did.
the following is what i did and what happened:

--
root@ttyp0[knoppix]# mkdir /mnt/win98_folder_f
root@ttyp0[knoppix]# smbmount //10.1.1.252/f /mnt/win98_folder_f
3589: session request to 10.1.1.252 failed (Called name not present)
3589: session request to 10 failed (Called name not present)
3589: session request to *SMBSERVER failed (Called name not present)
SMB connection failed
root@ttyp0[knoppix]# smbmount //10.1.1.252/f /mnt/win98_folder_f -o username=data
3602: session request to 10.1.1.252 failed (Called name not present)
3602: session request to 10 failed (Called name not present)
3602: session request to *SMBSERVER failed (Called name not present)
SMB connection failed

What does the error message mean? Would be nice if you could help me,

Thanks
Ulf
