Of course, we didn't find out that this was the case until after I had cloned our live server so that we would have a second (identical) machine that our developers could use to test integration with our order management system... one of the developers finally went to use it and told me that the Web Services Exceptions Console was giving an error... specifically, when you drilled down in the console view:
"Cannot access the exception service. Verify that the configuration file exists and contains the correct path to the exception service."
Not being an expert on the inner-workings on GP Web Services, I did the first thing that most anyone would do and searched for the error on Google for answers. I found a good number of forums where people had posted the same error and received a number of different responses, but it seemed that there were no reports of anyone having much success with them.
I was able to fix everything, but it required me to use bits of information that I gathered from multiple sources online, along with a little extra experimentation on my part (keep in mind, this was on a test machine and I also have a Ghost backup of the system).
After trying numerous recommendations about checking the .conf files to make sure they had the correct URLs listed and a number of other things without success, I decided that the best path would probably be to remove Web Services completely and then reinstall. However, this would fail, no matter what different things I tried. If I ran the MSI with the /uninstall and logging enabled, I would always get these errors in the log:
Property(C): ERR_DESTINATION_INVALID = The installation directory you've selected has existing files. Please select another directory.
Property(C): ERR_INVALID_USER_INFORMATION = The account you specified can't be found. Please verify the account information
Property(C): ERR_DOMAIN_REQUIRED = The account you specified is not valid because the SQL Server is on another machine and the account provided is a local account to this machine. Please provide a domain account.
Property(C): WRN_VIRTUAL_DIRECTORY_EXISTS = The web site already contains a "DynamicsGPWebServices" virtual directory, continuing with the installation will change the configuration of this virtual directory.
Property(C): WRN_ISO_CODE_NOT_SET_UP = An ISO code is not set up for all of the currencies in Microsoft Dynamics GP. You must set up the ISO code of all currencies before using the Web Services for Microsoft Dynamics GP.
...a couple of these errors made no sense to me at all, as I was performing an uninstall with a domain admin account... so OF COURSE there was content in the directory and it should not have had any user-related errors. I had also deleted the virtual directory from IIS at this point.
Anyway, let me get to the point.
I found a couple of blogs that were parts of the solution... thanks to 1. Remove “Adam Instance DynamicsSecurityService” in Add\Remove Programs.
2. In IIS Manager, delete “Dynamics Security Admin Service” Web site.
3. In IIS Manager, delete “DynamicsGPWebServices” and DynamicsSecurityService” virtual directories from the Web site that the Web Services for Microsoft Dynamics GP was installed on.
4. In IIS Manager, delete the “DynamicsSecurityAdminServiceAppPool”, DynamicsSecurityServiceAppPool”, and “GPWebServicesAppPool” application pools.
5. Delete the “Microsoft Dynamics” folder from C:\Program Files\Common Files\Microsoft Shared.
6. Delete “GPWebServices” folder from C:\Program Files\Microsoft Dynamics (This is the default location for Web site files.).
7. Delete “Dynamics GP Web Service Exception Management Console” and “Dynamics Security Console” shortcuts from Administrative Tools program folder.
8. Delete related Registry Keys for Web Services for Microsoft Dynamics GP 9.0.
9. Remove the DynamicsGPWebServices key under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
However, after all of that, he says that we need to run a bunch of SQL scrips to clear out the DB... which I never did and apparently didn't need to do (thank God). Still, I saw that Web Services was listed under "Add/Remove Programs" and I could neither successfully uninstall or reinstall/repair it, just as before all of this.
AT THIS POINT, I went through the Windows registry and deleted any keys I found that contained the words "Web Services" or "WebServices" (case-insensitive)... making sure that I wasn't deleting anything which wasn't related to GP - and I don't think I found anything that wasn't related. FINALLY, Web Services was no longer being shown as installed, and I was able to run the install without it thinking that there was still an existing instance.
Now, the problem I was having was that the installer was complaining that I didn't have the ISO codes entered for multi-currency in GP, and that it is required in order for Web Services to be installed at all. I found information about this on Steve Endow's blog, and learned that I just needed to go into GP as the SA and enter the required codes for the currencies that we are using (the codes on Wikipedia seem to be correct: Here). I entered said codes and was then able to run through the installer successfully.
Web Services is working properly now, and it feels great to have finally conquered that beast.

I also had to add some users here:
