I have a workgroup network of several WinXP, Server 2003 and Vista computers. My iMac can now no longer access shares on this network (initially it had no problems). The workgroup shows up, and all of the computers are properly listed, but when I try to Connect to one of the shares (which are all correctly shown on the dropdown list) I get the message: "The alias "<computer name>" could not be opened, because the original item cannot be found." Choices are <Delete alias>, <Fix alias...> and <OK>. When I select Fix, <Network> is grayed out and cannot be selected.
I have a nearly new iMac with 2GB RAM, OS X Tiger. No other Macs on the network.
Any suggestions?

1. Delete the Alias .. as once they stop working .. they never seem to be able to work properly again.
2. In the Finder use ... GO menu .. Connect to Server .. enter     smb://SERVERNAME/SHAREFOLDER (with you network names or IP addresses
3. IT will prompt for your network username/password and you shoudl be able to connect.

If you regularly connect to specific machines then you can use one of the methods here in this article to have shortcuts or automounts or applescripts do the wok for you

When I try to delete the alias I'm told "The operation cannot be completed because you do not have sufficient privileges for <server>."
If I follow your #2, I'm told "You are already connected to this server volume."

You might need to restart the Mac
Maybe disconnect from the network, reboot offline and log in as a user with admin rights .. then delete the alias

Then ignore the aliases for the moment .. and try using an applescript to connect

tell application "Finder"
    mount volume "smb://username:password@SERVERNAME/SHAREFOLDER"
end tell

another fix for the delete alias/fix alias file sharing problem.  found his at another web site:

I'm running Mac OS X 10.4.10 and this just solved the "delete alias / fix alias" error message and I'm now able to access my office's file servers

This is an excerpt from Drew McLellens All in the Head blog.

In a nutshell, the cause of the problem is the default security policy on Windows 2003 Server being set to always encrypt network connections under all circumstances. Whilst this is fine for most clients (especially Windows clients, understandably), the version of SMB that Panther uses doesn't support encrypted connections. Apparently this support exists in Samba 3, but not on the version OS X uses. The solution is to change the security policy to use encryption when it's available and not otherwise. Here's how.

From Administrative Tools, open Domain Controller Security Settings. Go to Local Policies then Security Options.

Scroll down to find the entry Microsoft network server: Digitally sign communications (always). Set this to Disabled.

The only thing left to do is to reload the security policy, as changes don't otherwise take effect for some time. Open up a command window and type:

gpupdate

This will buzz and whirr for a few moments before confirming that the policy has been reloaded. With a bit of luck you should now be able to mount a network share from the Windows 2003 Server on your Mac. As I say, I've been searching for this information periodically for more than six months, so if you find it helpful pass it on.
