I thought I would add a bit to the server installation documents. I struggled for about an hour trying to figure out what was wrong this AM and through some trial and error was able to get it running.
First, you can't have any instances of UO running on the PC you are installing to. This only applies to the server software. So, you cannot be connected to your shard on that PC, you can't be playing on someone elses shard, CentrED needs exclusive rights to your data files in the Ultima Online directory.
Second, depending on the Version of the client software that you are running on this PC, that is the version of Ultima Online, not the server software, you have to amend your map size. I finally ran across this chart on the CentrED Website, but, couldn't find it without doing a yahoo search:
The map sizes for Felucca and Trammel vary between different UO Versions. Before Mondains Legacy these maps were 768x512 in size but were enlarged to 896x512 afterwards.

Obviously looking at this chart, in order to edit different maps you are going to have to edit the cedserver.xml file to open a different set of MUL files AND modify the map sizes accordingly. PLEASE NOTE: the pdf documentation says that the config file is cedserver.ini. It appears at some point this has changed, it is cedserver.xml now. As near as I can figure the only way to change maps is to manually edit this file and restart the server.
If you place your cedserver.exe file IN your main UO directory, you should be able to run and connect. If you want to place it outside of your main UO directory, you will have to type full pathnames for each of the MUL files that cedserver wants to access.
I usually have a separate set of mul files for cedserver so it doesn't conflict with RunUO or the UO Client. Also you can have several instances of cedserver running, each on their own port. The config file to load is determined from the name of the server executable. So if you make a copy of "cedserver.exe" to "cedserver2.exe", the copy will look for "cedserver2.xml". Therefore you can even have multiple servers in one directory. I will also (sometime ... ;-)) add a commandline parameter to set the config file so one doesn't have to rename the executable.
