I am having intermittent communication problems on my Citect servers and clients, is there a way to log network trace messages between the servers and clients. I do not want to use or install a 3rd party network analysing software on the citect machines. 

Besides the normal 'ping' test, there is another method to trace and log the network traffic between 2 machines. Running a 'tracert' (short for Trace Route) command can help identify where the connection problems are occurring. The tracert program tests the connection from your computer to the target location you specify and every "hop" in between. Using this program you can determine at what location the data you are sending is running into a problem.

Steps to run the tracert command

- Click Start and then Run
- Type command and press Enter
- In the command window, type 'tracert IPaddress> C:\tracert.txt' (without the quotes) and press the Enter key.

A file will be created on your C: drive called tracert.txt that contains your route information. Please be patient when waiting for the tracert command to complete, it may take several minutes. When you are returned to the command prompt, then the trace is complete.

- Type exit and press the Enter key to close the command window.

I ran tracert, now what do I do?
Open the tracert.txt file. You will see 3 kinds of information regarding the route that internet traffic is taking from your computer to the client/servers:

- The number on the far left is the hop number.
- The next 3 numbers (with 'ms' after each one) is the length of time, in milliseconds, it takes for your computer to receive a response from the computer you are trying to contact. A high value, for example greater than 200 ms for broadband or 350 ms for dial-up, indicates that traffic is slow, and can cause latency. Asterisks (*) indicate that your computer did not receive a response from the computer you are trying to contact at all, which can keep you from connecting to the servers altogether, or cause you to be disconnected abruptly.
- The final piece of information is the DNS (or 'name') and/or the IP number of server you are trying to contact on this hop. If you did not receive any responses from this server, you may receive an error message such as 'Request Timed Out' or 'Destination Net Unreachable'.

If you see any error messages or asterisks in your tracert.txt for the hops before you reach the client/servers, you may need to contact your network administrator and provide them your tracert results for further assistance.
