"I had exactly the same problem, whatever I entered into "connect to server" window, I get an invalid URL error. I digged up the samba_fix for tiger from my HD, and it worked."

The file were looking for is named, Simple Samba Fix for Tiger Update 10.4.6 Intel x86, or SambaFix_for_10.4.6.pkg.dmg
This should work, but i am unable to download the file anywhere...
EDIT:
I GOT IT FIXED!
Didn't have to use the samba fix
Check your System/Library/Filesystems for any alias and remove them (mine was afpfs)
Reboot
If that doesnt work, go back to that location and move the URLMount folder to your desktop (make sure it isn't in the filesystems folder anymore)
Reboot
Now move back the folder and repair permissions with disk utility, and reboot.
Everything should be working now, atleast it did for me
Edit2: Still when trying to connect to a other pc using finder (shared tab) it says the ip may be wrong or the pc is disconnect, but when i connect to the ip directly it works...
Some proof
