I have several VPN's coming into the main office using 5xp's in the field connecting to NS25 in the main office. I used to get an email everytime they would go up/down, but they've stopped recently. I'm still getting other messages like IP Spoofing alerts, etc, but not the VPN messages. Anyone...

Excuse the cross-post, I also posted this in the Exchange 2007 forum, but I need to find an answer fast: Since our migration from Exchange 2003 to Exchange 2007, Outlook 2003 users are constantly prompted to enter their user name and password. Checking the box to remember password has no...

Since our migration from Exchange 2003 to Exchange 2007, Outlook 2003 users are constantly prompted to enter their user name and password. Checking the box to remember password has no effect. Every 5 - 10 minutes they're prompted to enter it again. If they click cancel, Outlook switches to...

Anyone know the limits of how many/what size files Vista's Compressed (Zipped) Folders can handle? If I select more than a dozen good sized files, it only puts 6 or 7 in, skips the rest and leaves a bunch of .tmp files in the folder with the same name as the .zip file. I've tried this on...

I'm using Group Policy Editor on Server 2003 to manage Windows Firewall settings in an mixed XP/Vista desktop environment. I've made the correct settings to allow ICMP echo, and it shows up in the inbound rules on the workstations, but the Vista machines still do not respond to PING and don't...

I've modified the default Outlook 2003 message form to validate that employees enter a valid job number in the subject line of each e-mail. The problem is, when they don't, the alert box that comes up pops up BEHIND the message they're typing and the Outlook button doesn't flash to let them know...

Anyone know how to remove or reassign Netscreen User Objects? Most of mine say they're "In Use" and won't allow me to modify, remove or re-assign them to different groups. All the Juniper documentation indicates how to create users, but not delete or modify them. Am running a Netscreen25 with...

We have a Netscreen-5GT at a remote site that connects to the main office over IPSec VPN. Outlook users are unable to stay connected. Microsoft says it's because of the Proxy ARP on the firewall, but I don't see anywhere to disable it. Does anyone know where it's located? It's running ScreenOS...
