  • 1. A way to connect a remote CD-ROM share
    Is there a way to mount a Remote CD drive to a virtual guest server like an ISO is mounted. We are setting up a console system and would like to have people place their CDs in that system instead of the server itself. This would also be quicker than creating an ISO as well. Thanks. Rob
  • 2. How to disable Time Synchronization with Host machine
    Hi, I am using Microsoft Virtual PC 2004 SP1. The VPC that I run, automatically synchronizes the time with the host machine. How can I disable this feature in the VPC? Thanks in advance. -Amit
  • 3. Vista+VPC 2004+vmadditions.iso
    Hi, I just attended the PDC05 and get the "Goods", including the Windows Vista Beta 2. I'm trying to install it using Virtual PC 2004 and took me several hours, unfortunately unsuccessful. I tried to consult the matter with the virtual_pc_guy at the Big Hall area and told me that there are issues. Now, I read some blog/wiki that there has been a vmadditions.iso that we can use with VPC 2004 to work with Vista. Can you help me on how to use it step by step? Thanks
  • 4. Windows Update won't work. VPC 7.0 MAC 10.4
    After running Windows Update I get the following error message.... The website has encountered a problem and cannot display the page you are trying to view. The options provided below.... ERROR NUMBER : 0x80072EE2 A search for solutions to this error number suggest adding the update sites to my trusted sites and lowering security, etc. I have tried all of these things including turning off firewall and lowest security settings. Does anyone have other suggestions? Thanks in advance. Dave

1) Virtual PC emulates a CD reader - like all other emulated hardware, it 
makes no difference what devices the host machine actually has...

2) Have you installed the DOS CD drivers in CONFIG.SYS and AUTOEXEC.BAT...?

2.VPC 2007 DOS CDROM not fully useable


I have a DOS 6.22 installation on VPC 2007. I have manually loaded the
DOS Additions and shared folders is working great but I am having
trouble with the CDROM.

device=C:\VMADD\cdrom.sys /D:idecd001

mscdex /D:idecd001 /L:E

The drivers load fine and work fine when I attach the physical hard
drive. However, when I attach an ISO CD image I can browse all the
folders but cannot access anything. I can use DIR and see files and
even use CD to change directories. If I try to access anything it
tells me it does not exist (file not found).

Has anyone run into this before?


3.Getting DOS 6.2 & Win 3.1 to Recognize the CD Drive

How do I get DOS 6.2 & Win 3.1 to recognize the CD drive?  Normally with 
these OS's one would install drivers for the CD drive that load during the 
boot process.  However, even with a readable CD in the drive, and specifying 
the VPC for this installation to use the physical drive, when I reboot the 
VPC, the drive spins up, but when DOS tries to load the driver (MSCDEX.EXE 
/D:MSCD001 /V /M:15), I get an error message that the drive cannot be 


4.VM additions in dos VPC - not working

 	Having installed Virt pc on trial, dos 6.22 win3.11 I find the CPU is 100%
and the application hangs, pity as it does what I want in 3.11. Anyway some
threads suggest SP1 or VM additions (is VM additions within SP1?) so I try to
install SP1 - it wont proceed, as the pop up box says as there is another VPC
install cant go ahead, please remove VPC and start again. So I try and then
it says cant install SP1 as there is no VPC on the computer. Where do I go
from here?

Please note I can find DOS drivers for my laptop CD so do I have to add
via host OS.

PS - I am wasting my time and is VPC not really capable of DOS? 

5.VPC 2007 support for Win98se Dos Window

Don't make assumptions about pre-release software.  I recommend that you 
uninstall and reinstall VPC to ensure that all the bits are refreshed.  I 
found a couple of issues on one box by upgrading and not removing first.
