Printer won't work after installing ZoneAlarm

Greetings.

I've just installed ZoneAlarm 7.0.483 and now I cannot print using my Dell Photo AIO Printer 922. I was able to print a few days ago before the install. Also, when I shutdown ZoneAlarm completely I still can't print.

Does anyone have any ideas?

Many thanks!

After doing some more troubleshooting I've found that I receive 3 of these errors under System in the Event Viewer every time I try to print. They occur about 2 minutes apart:

Does this help in troubleshooting?

I have Windows XP Pro SP3, also...with all the latest printer updates.

Thanks.

go to the run->services.msc and ensure DCOM is started
