Answers to Frequently Asked Questions regarding Synchronet and Microsoft Windows operating systems.
Why don't DOS programs (e.g. editors, door games) run on my Windows Vista or Windows 7 32-bit system?
There are 2 new requirements for 16-bit DOS programs to work under Synchronet-Win32 on Windows Vista and Windows 7 (32-bit):
- You must have
SBBSEXEC.DLLrev 38 or later (this is included in SBBS v3.14a).
- You must copy
SBBSEXEC.DLLto your Windows
Why won't DOS programs run on my 64-bit computer running a 64-bit version of Windows?
Microsoft does not include Virtual DOS Machine (NTVDM) support in their 64-bit operating systems. Synchronet for Windows relies on NTVDM for 16-bit DOS program support, so you need to either run a 32-bit Windows version (e.g. re-install, use dual-boot, or run in a Virtual Machine) or forgo DOS programs on your BBS. Yes, you can run 32-bit Windows versions on a 64-bit (x64) system.
How do I keep external programs (doors) from popping up windows and stealing the keyboard/mouse focus?
Why do external programs that use socket I/O (e.g. Synchronet Blackjack, Synchronet BBS List, DoorMUD, SEXYZ) not work on my BBS?
Some “security” software (e.g. firewall and anti-virus programs) will interfere with the inheritance of socket descriptors between processes. One such program is the ZoneAlarm Security Suite. Another is NOD32. I don't know if this is an intentional security “feature” or a design flaw. If you have this (or similar) software installed, it may need to be disabled or completely un-installed for socket inheritance to work again.
Another potential cause of this Windows problem is malware (viruses, trojans, etc.) which disable the Windows Firewall Service. Even if/when the malware is successfully removed, the damage done to Windows (and specifically the registry) remains. One recent sighting of this problem was rectified with the following steps (found here):
- In Registry Editor, browse to the key
- Right-click SharedAccess, and select Permissions…
- Click Add.
- In the “Enter the object names to select” field, type “NT SERVICE\mpssvc”. Then click Check Names. The name should change to
- Click OK.
- Check Full Control checkbox in the Allow column.
- Click OK.
How do I setup my BBS to support dial-up modems/users?
Use the SEXPOTS utility in combination with Synchronet for Windows.
Why is the console output of some 16-bit DOS programs not intercepted/redirected and sent to the remote user's terminal?
Check that your
C:\WINDOWS\SYSTEM32\CONFIG.NT file does NOT include Microsoft's
ANSI.SYS console driver. Use of this
ANSI.SYS driver defeats the interception of console output from some 16-bit console I/O programs.
