There is some confusion here. I am almost certain the intent is to block access to a http server running on port 80 from a telnet client. Telnet can connect to any server that utilizes TCP on any port by simply specifying the desired port after the address. This can be quite useful for...

It looks to me like you are trying to access the VPN server using a domain name that includes then domain name used by a third party to host your website and email. The VPN server is hosted at your location over a DSL connection. This will not work without changing DNS information for that...

This is fairly simple with the proper tools, impossible without. You need to use the Connection Manager Administration Kit (CMAK). The CMAK is included with the Administration Tools for each of the recent server versions of Windows. You do not need the server version to run the CMAK as it can...

A few things that may shed some light on your problems: From the XP machine, try to access one of the Vista machines by IP address. Click on Start, then Run. Type "\\xxx.xxx.xxx.xxx", substituting the IP address of one of the Vista machines. Note the slashes are backslashes -- not the one...

Yes, you need a static route on the location B router. Network 192.168.68.0 Mask 255.255.255.0 Gateway 192.168.0.xxx replacing the xxx with the IP of the computer that is actually making the VPN connection. Without this route, traffic from the other computers for 192.168.68.x goes to the...

In order for this to work, your two locations will need to have unique network addresses. If location A is using 192.168.68, location B must use something different. If both network addresses are the same, routing will not be possible. I would suggest that you use your Server 2003 at location...

About the only thing that I could guarantee you at this point is you are not seeing the 0xD1 error resolved by the hotfix you have located. The numbers after the stop are important in determining the cause of the error. I would suggest you take a picture. Camera phones usually will do the...

I would guess that you are indeed having permission problems at this point. Accessing computers by name across a VPN connection can be problematic regardless of your VPN solution. A DNS server, or alternatively a WINS server can clear some of those issues up. You might want to try accessing...

You haven't provided enough information to even take a good guess at this one. First, what you have provided. Please verify that this is correct. 1)You have a server that you have configured to accept incoming VPN connections. This server is obtaining a public IP address from your cable...

You will never receive the "CONNECT" message because you are not technically "connecting" to a modem. You are connecting to a device that listens for DTFM tones, the same tones that are used for dialing. If you are using a voice capable modem, you should in theory be able to listen for the...

This could well be a hardware issue. I would suspect a cable first, although a network card or switch port or event the switch could be causing the problem. The "connection reset by peer" does not specifically indicate a problem with Samba or the linux box. I did a bit of searching and did...

Mapping a drive over the raw internet is a very big security issue. You really should do this over a VPN connection, which would eliminate the need to open additional ports. If you really must, then TCP 135, 139 and 445 and UDP 137 will need to be opened.

The network in this case is 67.49.0.0, the broadcast is 67.49.7.255, and everything in between is a valid host address (including 67.49.5.0). The subnet mask controls the size of the network. A 255.255.255.0 (or /24) subnet specifies that the first three numbers are network address and the...

Inbound mail depends upon how much control you have over your DNS record. Adding a MX record to DNS will allow you to point inbound mail to a mail server at another host. Outbound mail can be more of a problem. You can send outbound mail for your domain from anywhere, however if you are...

For what it is worth, the information indicated for the DL-500/504 is listed in the section for the DL-502. I would be concerned about any DL-5xx model. If your lease time were increased to something reasonable, it would certainly help your problem. I would guess that your ISP also services...
