"user name may not be the same as computer name"

I get the above error when trying to add a user name that is the same as the computer name.  If I change the order...create the user name first and THEN rename the computer, it works.  My question is...I know that I CAN get this to work but SHOULD I get it to work?  I am implementing a W2K3 domain if it makes any difference.  I know Microsofts stance on it via  Q310845 however, does anyone have any real world experience where this has actually caused a problem.  I haven't found much on this on any of the forums.  Again...I know what Microsoft says but am looking for real world here....

Thanks

My current installation base of computers all have the user name and computer name match.  We are going to be rolling out XP and this is an issue according to Microsoft.   Before completely changing our naming convention, I would like input on this issue.

Ok, I agree with gjacknow1.

As your network grows and expands inito newer operating systems the current naming convention that you have will probably come back and bite you later.  If you don't have any concern of this, I am going to sugest that you add the newer OS and any others to a different subnet or workgroup so that you can manage them easier at a later time as you begin to decommission the older machines. This will keep things separate between the old and the new.

Thanks to all who have responded so far.  I know all the theory about what could happen....but again....I am looking for real world here.  Has anyone actually experienced problems with this...and if so....exactly what were they?

Not sure what you mean, TheVirtualOne....

It was well phrased theory...however....it is not an answer to my question..it is not an answer from experience.  Again...I am very familiar with the theory behind this so I was not looking for a theory primer...I was looking for someone who has experienced this problem.  I will split the points since you were all so kind to respond but unfortunely, my question still is unanswered.....

I would say, that the best thing to do is try it out.
Get a few test machines and set them up like you have outlined, install the apps and services you use from day to day, and have a couple of users play with them for a while.
If you start getting all sorts of weird problems, then you'll know that it's not going to work.
If it's fine after a week, expand it.

As you say, all the posts are indeed theory and personally it would be interesting to see if anyone out there actually did do this with good/bad results.

As you have spent the points on us, let me know if you'd like this question re-posted and I'll pay for it out of my own points.
