Some questions:
Can you ping svr88 from a client that can't webbrowse to it?
Are the clients, svr88 and the local nic on SME on the same subnet?
if you do a ping -a svr88 what name comes back?
Assuming you have Windows clients, if you add svr88(or whatever name comes back).abc xxx.xxx.xxx.xxx to C:\WINDOWS\system32\drivers\etc\hosts file, can that client then browse to
http://svr88.abc/page? (This is not a fix, but shows you do have a name resolution issue)
You might want to take a look at the results of an ipconfig /all command on both a client and svr88.
