I found tek-tips trying to solve the same ZoneAlarm alert situation. I have completely reloaded and updated Win 2000 Pro, setup a new small Netgear network with ADSL access (including a print server and 2 printers), run Norton anti-virus (up to date) and have added Zonealarm Pro. In the first few hours running, ZA has blocked 6 attempts by spoolsv.exe to access an IP identified as my ISP (PIPEX). Printing seems to work ok. I still have to completely reload, set up and connect the other 2 PCs that will be on my network (Windows ME and HP), and will be interested to see if they experience the same problem.
Any answers will be welcome.
