I have heard of this problem when the LAN buffers were not tuned properly,      
you may want to make sure you have enough big-buffers and work-buffers          
at the server.  You may also want to make sure you have two Token Ring          
transmit buffers defined, instead of the default of one.                        
                                                                                
We have never had this problem with our LS 2.0 on OS/2 2.0, although we         
do sometimes expierience lost print jobs.                                       
                                                                                
There is also a fix available for LAN Server, and XCOPY fix was included in     
this.  If it not at ftp-os2.nmsu.edu, I can post it there, just let me know.    
Try the watson.ibm.com ftp site also, it should be there.
