Finder — establishing connection to server takes forever

Hello,

I already found an archived discussion (https://discussions.apple.com/thread/2188921) which explains my server issue.

Anyway I will write some further thoughts down here and I don't use VPN.

Our company with about 40 (Lions, Mountain Lions and Snow Leopards) employees runs a Xserve with Mac OS X Server 10.6.8 Snow Leopard.

The problem I have consists of the File Sharing Service over AFP and/or SMB (I tried them both).

Most of our clients have no issues connecting with Finder to the file server and mount shares.

But a few of them have issues regarding the connecting time (~1–2 min.) until a share is mounted successfully.

After the connection is established there are no further performance issues.

Anyway this waiting time is annoying.

I don't really know whether this is a server or a client issue.

The issued clients are OS X 10.7 Lion and OS X 10.8 Mountain Lion respectively.

What I already tried was creating a new user on one issued machine, but didn't help.

I'm looking forward to get some support with this.

Thanks in advance.

Regards,

Delivery Boy
