Short solution for short problems

/3GB option in the Boot.ini (cannot open large files)

I installed WSS 3.0 on a windows 2003 server. Everything looked OK. I was thrilled to get the installation so easy and correct in the first try. But when I start using Sharepoint, I noticed that some files opened and other didn't. What was going on here? After digging for hours in the WSS administration, I couldn't find the problem. Then I started to google for a solution, but I can tell you, it was not easy. After testing a little while I noticed that files larger then 200Kb didn't open, smaller files did. So There was some kind of limitation on the server. I noticed that the files where correctly in the DB. So I concluded that it was not a Sharepoint problem. When I finally hit the correct search words in google I came up with this solution:

The Windows Server 2003 /3GB switch is not supported in Windows SharePoint Services 2.0 or in later versions or in SharePoint Portal Server 2003 SP2 or in later versions.

So when I removed the /3GB part in the boot.ini file and rebooted the server, everything works fine. What a relief. I hope you didn't had to google as long as I did to find this solution!

I had the same error working woth word documents. But the error messages can be very misleading. Here are some examples of error messages:

or:

If you are having this kind of errors or even an error like: locked of checked out by ... and it doesn't make sense, then try firdt opening a small or empty document. If that works, you know it is this problem and you know the solution.
