Disabling Windows Messenger Service

If you're running a Microsoft Windows operating system, you could be subject to annoying messages that pop up spontaneously. We're not talking about popup windows that are part of web browsing, rather messages that are contained in what look like alert boxes. Windows includes a facility called the "Messenger Service" that was originally designed to accomodate communications between local computers. Unfortunately this function has been abused by those who think it's all right to prey on others as long as there's the possibility of making some money. Messenger Service is subject to abuse because there are no controls on it: if it's enabled and not protected by a firewall of some sort, anyone can make use of it to display a message on your computer.

We know of at least one program that makes it easy for you to turn this service off (and to turn it back on, if need be): Steve Gibson's "Shoot the Messenger" program. Be aware that we don't make any representations about programs that you get off of the net: in fact downloading and running programs is inherently risky. We mention this program for your reference only: take an appropriate amount of care if you should decide to use it.

If you're on a dialup connection to MV, you may be protected from these popups by some of our temporary packet filtering, which we put into place a couple of months ago to help with the spread of a couple of nasty viruses. (This filtering is indeed meant to be temporary, and we'll address that subject a little more next month.) But it's still a good idea to turn off services that you don't need, particulary if these services can be accessed from outside your computer.

 

Changenotes: monitoring Web site changes

Sometimes you find a website that has interesting content that changes now and then, but not often enough for you to check it regularly. Some of these sites have ways to let you know when there are updates (whether via an RSS feed, mailing list, or other methods). But sometimes the site does not provide any such notification.

We ran across a site recently, www.changenotes.com that lets you watch one or more sites for changes. Although we are aware of other such services, this one stood out for a number of reasons. It combines notices for all sites you are watching into a single email message, with a maximum of one message per day. Plus, it doesn't require you to install any tools or toolbars, nor does it require you to enable any fancy browser features to set it up. The notification email message may contain some advertising.

(We have no affiliation with this service, and don't really know any background about them: we're just passing the link along.)

 

Access number changes

We've been telling you for a few months now to expect the 1-500 NH statewide access number to go away, and it is now indeed gone. The background in brief is that we took up this service while Verizon initially deployed it. Verizon decided not to tariff the underlying service in NH, preferring only to offer a more layered service instead. We certainly wished that Verizon had decided to file the tariff and offer the service, but we had little choice once they decided to withdraw it. On the up side, we were able to give you several months notice.

Relatedly, we moved several of our underlying access numbers to another carrier. These included Nashua numbers 603-886-7124 and 603-886-6688, plus the Concord number 603-227-2100. Since these calls are being handled by a new carrier, we'd advise you to check with your phone company to make sure you understand any charges incurred, particularly if you are calling them from a non-Verizon phone (e.g. an independent telco)

 

Access number change fallout

There were a couple of things relating to the access number changes that did not go as smoothly as we would have liked.

In the case of the Concord number (603-227-2100), the change to the new carrier took place almost instantly, except in the Concord area, where it mattered the most. Something about the way the change was propagated got delayed, and callers in the Concord area got a busy signal when they called this number. After some days (a week at most), the change went through completely and the number resumed working for all callers. Most people were able to use one of our other numbers. But if you were severely inconvenienced, please contact us and let us know and we'll provide a small credit.

Some others who were placing ISDN calls to the old 1-500 number were affected. The 1-500 number supported circuit switched data ISDN calls (digital calls at 64000bps) as did the 227-2100 number. Our standard dialup numbers support data-over-voice ISDN (at 56000bps) but do not support pure data ISDN. Frankly because of the way ISDN calls are tariffed in NH, we were surprised to find people who were making data ISDN calls. The carrier that we use for our primary numbers has identified the problem with data ISDN calls and is working on correcting it, but we have no estimate for this repair.

 

Email: extended addresses

Just a reminder that if you have a mailbox at MV, you can create and use extended addresses. Say you have an address of user@example.mv.com that is delivered to your mailbox named "example-00" on our mailbox server. An extended address of the form "user-anything@example.mv.com" will also be delivered to that mailbox. The extended address is formed by adding a hyphen to the username part, and any combination of letters, digits, and hyphens following that. You can use these extensions to create unique email addresses for specific purposes. If you give out such an address and decide later that you don't want to receive any more mail for that address, you can filter it out using our mail filters (available via the webmail interface at http://webmail.mv.net/ . Or you can explicitly configure the extended addresses that you will accept, and block all others.

 

Some dialup account changes

We are making some pricing changes to dedicated dialup and telnet-only shell accounts, as well as introducing a new standby dialup account.
