Title:Making the Dynamics GP User ID field blank on Terminal Servers
Description:UPDATE: It has been several years since I had to deal with this, so it seems that at least one of my proposed solutions are outdated. David Musgrave has weighed in with his feedback in the reader comments.

This is an oldie, but a goodie.

Dynamics GP was designed with certain assumptions in mind. For instance, as a client application, GP assumes that a user would like to save certain settings and preferences so that they are retained for the user the next time they launch GP.

This typically works great on a single client PC, but when you install Dynamics GP on a Terminal Server, sometimes this can be annoying.

One of these saved settings is the user ID of the last user that logged into GP. On a Terminal Server with numerous users logging in and out of GP throughout the day, the last User ID is generally a random user ID. When a user logs in, they have to substitute their user ID.

Some GP customers don't even notice this "feature", but other customers consider this behavior very annoying or a security issue, and demand that it be changed.

Fortunately, there is a solution. Two actually.

Option 1 is to use a VBA script to blank out the User ID field when the GP login window is displayed. This solution is discussed in KB Article 859129, "Blank User ID in Great Plains". It is simple to implement, and in my experience, works well.

UPDATED: Ignore this second suggestion! See reader comments for more information.

Another solution that I learned somewhere is to make the Dex.ini file read only. Since the Dex.ini contains the SQLLastUser setting that GP uses to populate the User ID field on startup, if you make this setting blank, and then make the Dex.ini file read only, GP will always display a blank User ID value.

Although this technically works, there are some possible drawbacks to this approach. As I mentioned, GP saves several settings and preferences to make users' lives easier, so by making the Dex.ini file read only, you are not only disabling the last user ID feature, you are preventing GP from saving dozens of other preferences, some of which may cause new annoyances for users, or even problems for GP.

I was unable to find the Dex.ini solution in the Knowledge Base (it may be in there, but my searches didn't locate it), so because of the potential side effects, I suspect that it may not be a supported solution.

But just thought I would share both since I've seen both of them implemented.
