Web Server Crashes on port 80.

I have a webserver app that will crash when run on port 80. I am now running it on 1025 and it seems to work fine, but I need to run it on 80, but everytime I switch it to port 80 the application will crash within 30 mins. I am running this on a windows 2003 sp1 machine. There is no firewall to block 80. Does anyone have any suggestions?

Re: Web Server Crashes on port 80.

A couple of questions for you...
1) What do you mean by 'crash'? How do you know its crashed?
2) Can you look in the Windows Event Viewer to see if there are any warning/error messages in the Application or System logs around the time of the starting or crashing of your web site on port 80? If so, anything that suggests the issue. If you don't understand the errors, try posting some of them here.
3) Is there any other web server running on port 80? If your running Internet Information Server, open the Internet Information Server Manager (mmc) console and click on "Web Sites" and it should list all the sites in the right pane. If you have anything 'running' on port 80, it will conflict.
4) Are you running Apache or any other web server on the system? If so, you're going to need to look at those configurations as well.
5) How about any other applications that might have a built in web server?

Let me know.

Corrupt MYOB data file

Our MYOB 14 .dat file is crashing. We suspect a corrupt entry in the database. The file will open but as soon as we trying to do anything the program closes and produces the following error: MYOB must terminate. Termination Code 1284 Important Details: Error -3000 in DMGTEKey (5037:7000:69) Seems to be the same error every time. We have tried running MYOB's Verify and Optimise tools with no luck. Each time either tool is run the program crashes and displays the error: An error occurred while attempting to compact the database. DM Error = (-3000-5049-7000-158) Restoring from a backup is not an option as last backup was 3 months ago. So looking for solutions to fix the current file please. Will not be satisfied if the solution is to take it to MYOB. Need someone who can actually dig around inside the file and correct the errors??

Problem configuring client station

easiest solution is to avoid their sync stuff all together, i've almost never gotten it to work correctly. what i generally do is set up the client station as a "stand-alone" and put the server address for the server name. that usually does the trick, only lick is that if the server goes down, your toast, the client goes down too.

MSoft Word 2007 crashes with Saved Normal document Template msg

Get a copy of AVG free and run a full scan across your system. if that doesn't work and If you are running xp or above you might be able to run a system restore back to a point before this problem started. Do a search for "System Restore Wizard" in the windows help, that is the easiest way to start the wizard. I don't think it is in the menus anywhere. That should de-activate the virus but the files will still be on your system. Make sure you have antivirus installed and updated on your system. Be very wary of any changes to Unless you change it directly any warnings about this file are caused by a virus.

Running system restore will also disable any applications you have installed since the date of the restore point. It does not delete any files. You will just need to reinstall any applications but that shouldn't be a big deal.

Hope this helps.

SQL server won't work on my laptop

Two ways to access your server. First, make sure the SQL Server Service is running. Start | Run | Services.msc | Enter. Look for Microsoft SQL Server Service and that it's running. Or Look for the SQL Service Broker icon by the clock and see that it's running. The default instance of SQL Server uses the Hostname. Start | Run | Cmd | Enter. The type hostname. This will be the name to access to server. Then type IPCONFIG, this is then the IP address that you could also use to access it.

SQL Server runs on port 1433, so any firewall has to have it open.

Open Query Analyzer, type in the hostname or ip of the local box, type in "sa" and the password for sa (if setup in mixed mode) or Windows Authentication.

Once you login in, you should now see the databases in the Tree on the left side under the Server | Databases node.

Your description though states "SQL Server won't work on my laptop". TO answer this, the only two SQL Editions that work on anything other than "SERVER" software is SQL Professional and SQL Developer. All others have to be on a "SERVER" platform.
