Configuring the firewall on a Windows XP NetWorker client

This problem has already been described in Legato Technical Bulletin #399. However, In addition to that bulletin here is some additional information which might be useful.

The installation of Window XP Service Pack 2 will install a new version of ICF (Internet Connection Firewall). This will be done automatically and without any feedback You do not even have the chance to change the default settings. Unfortunately, this will break a running NetWorker environment.

A Windows XP computer is supported as a netWorker client

Manual backups from the client will still work ...

nwxp-nsrfw

... but server-initiated backups will fail

This is not a NetWorker problem but an XP issue - the firewall on the XP client needs to be reconfigured.

In general, you can do this in different ways:

  • either for all domain-wide XP clients - If a domain is present
  • Or, individually for each XP client - If a domain is not available

Legato have developed a small routine called nsrfw to assist in resolving this issue. You can download this utility from ftp://ftp.legato.com/pub/NetWorker/Updates/WindowsXP/ProductAlert-XP/nsrfw.zip

NOTE: You will need to unzip the file to a temporary location before you can install it.

Installing nsrfw

To install the software, simply double-click the file nsrfw.exe. For example:

nwxp-nsrfw

The installation is done in a second

nwxp-nsrfw

Of course, the program will not change the NetWorker port configuration

nwxp-nsrfw

However, automatic backups still fail with the same problem. Obviously, installing the software was not enough to resolve the issue - you must configure it also:

nwxp-nsrfw

So I added the new firewall configuration:

nwxp-nsrfw

This solved the problem
