Navision network broadcasts

enny

Hello everyone,

we have a little problem in our company with Navision. We use (Client) Navision Attain 3.60 on Win2000 Terminal Servers with Citrix MetaFrameXP. The Navision Server is with MS SQL2000 Server on a Win2003 Server.

We noticed that after an user opens Navison on the TerminalServer the Terminal Server makes network broadcasts (some every second) even the users doesn't do anything in Navision. And this network brocasts multiply with every more user on the Terminal Server.

Here are some details of these network broadcasts packets/frames:
Source IP: IP address of the Terminal Server
Source port: 45179 - (45197)
Protocol: 17 (UDP)
Destination port: 45178
Destination IP: 255.255.255.255
Readable data in the packet: ANNOUNCE\TS001\4724\2995\2.0\user1\3.60.0.15069\Department - Microsoft Navision Attain

I checked the Navision Server and there is no listen port or communication with port 45178. I have no idea why Navison does that and how to stop that.

Please can someone help or has an idea?

This is the first time I hear this. Navision does not use UDP protocol. My guess you should check terminal services. There must be a service that broadcasts everytime an application starts.

I know this post is about 4 years old, but in case you are wondering...

Our organization experienced the same issue recently, and we were able to determine that the broadcast traffic is originating from ExpandIT (our Navision user management software). If you are using ExpandIT to manage your Navision user licenses, you may want to explore this as well.

I currently have a support ticket open with the ExpandIT's support staff. However, we have not yet found a way to configure the software to only send network packets to our ExpandIT management server.
