I've noticed lately that I am getting several undeliverable messages a day. The strange part is that these messages are messages that I never attempted to send. Most of them tell me that the recipient could not be reached. They look like legitimate System Administrator messages as well. Can...

When I try to connect to our Windows Server 2003 VPN, I'm getting the following error: "812 The connection was prevented because of a policy configured on your RAS/VPN server." However, I can connect to our VPN no problem from an XP machine. Any clues would be greatly appreciated.

When our users go to browse the internet, they first need to authenticate to our firewall. Part of this authentication process requires the user to download files from the firewall. Any user that has IE6 that is using WinXP is always prompted to download the files. Is there any way to have IE...

I'm attempting to make a form that will input data in to a table. I have a combo box that gives the user a pulldown box of info that they can chose from. However, regardless of what they chose, it always shows up as "1" in the table. For example, if their choices in the combo box were Yes or No...

We just got two Cisco 1700 Series routers in and we want to use these routers to replace our existing 1601 routers. Is it as simple as saving the config off the 1601 routers and then restoring that config on the new routers? If so, what is the process? Thank you!

For the past year we have been using Netsaint which is a Linux based program that monitors computers, routers and switches and sends alert emails when those devices go down (or are no longer pingable). We've decided to migrate away from Linux so I am trying to find something to take it's place...

We have our system configured so that every user must authenticate to the firewall before they can browse out to the internet. For some reason, after a user logs in, they get a screen telling them "Completing login process, please wait." However, the screen just sits there. Further down the page...

I am unable to send email to certain domains like AOL because my email server doesn't have a reverse DNS lookup. I'm a little confused - does this record get set up on my exchange server or do I need to take care of that at Network Solutions Website? I was already on Network Solutions website...

I have a printer that I am attempting to share on a Windows XP machine. Everyone can access the printer fine except for one computer that is running Windows 98. We plan on replacing the 98 PC but until we do I need to figure out how to get this PC to see the printer installed on the XP box. When...

We are currently in the process of switching ISP's and I'm curious as to what all we need to do to make sure that our website, email etc will work. We have all the new public IP addresses available to us. We currently host our web server and exchange server on site. We also have an account with...

Right now we are using 172.25.0.0/16 255.255.0.0 for our numbering scheme on our LAN. I need to renumber the network to 192.168.0.0 255.255.255.0 scheme. I'm trying to figure out what kind of headaches I might run into during this change. It's a very small network - consists of 10 clients and 1...

I have several T-Mobile Dash phones that are wirelessly synchronizing with my Exchange 2003 server through ActiveSync. I've had several users ask if there is a way to access the global address list from the phone. Right now, if a user wants to email someone in the organization that isn't in...

I'm attempting to sync my Dash phone wirelessly through activesync. I'm using Form based authentication and SSL on my exchange server. I exported my certificate from my OWA site and installed it on my device - but even after doing that I'm still getting an error telling me that my certificate is...

I'm attempting to set up my T Mobile Dash phone to wirelessly sync with my Exchange 2003 server. It looks like I have to set up my server to be capable of wireless synchronization. Can anyone explain exactly what I need to do to make sure my exchange server is set up for wireless sync?

I have Exchange 2003 running on Windows 2003 Standard Edition. I have the "log in with forms" security enabled. For some reason, certain users can't log in to OWA. They will get the error "You could not be logged on to Outlook Web Access. Make sure your domain\user name and password are correct...

I'm trying to figure out which computers (IP addresses) are plugged in to which ports on my Procurve 2650 Switch. I'd rather not have to trace the physical wires all the way back to the actual computer. Is there anything that could tell me which clients are going into which ports?

Does anyone happen to know what the process is for networking a DOS computer to an NT network? I thought there were some install disks that you could create from the NT Server CD? Thanks!

I have no idea what one of my users did but for some reason, any time he launches Outlook or attempts to contact the exchange server, it automatically launches his only VPN connection. I've looked at everything and can't figure out why it's doing this. Is there somewhere in the local mail...

We have a pretty strict security policy at our company. Right now, our servers are in an IP range that do NOT have unrestricted access to the internet. In fact they have no access past our firewall period. What ports should we open in order to allow Symantec Corporate Edition 10 to pull down...

Right now I have two DHCP servers on one subnet mask. A client can only get an IP address from either server if they have a reservation on that server (based on their MAC). The odd thing that I'm seeing is, let's say user 1 gets an IP address, gateway, dns and dns suffix from server 1 because...
