SYMPTOMS
Drive letters mapped to other network drives by the SUBST command may not
show up in the Drives box of a 16-bit Open common dialog box. This happens
for all 16-bit programs that use GetOpenFileName() to display the File Open
common dialog box.
CAUSE
Internally, there are two threads working together to display the Drives
box; the lack of synchronization between those two threads causes the
symptom described above.

STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
