Solution for "Can't browse drives on network computer which has ATI installed...
You may find that you can't access the drives on a network computer which has ATI installed. The likely scenario for this issue to occur is if the network computer's hard disk has more than one partition or has more than one hard disk installed, and/or also has anti-virus and/or anti-malware software installed.
Cause:
The root cause of the problem simply is that the computer with ATI installed runs out of I/O request packet stack space. This problem also can cause I/O error messages to popup when using ATI to perform backups to external USB drives. (Also note that you can get I/O error messages for hard disks which you have installed in an external USB enclosure and the hard disk's timing isn't compatible with the chipset used in the external USB enclosure, or the external USB enclosure uses a chipset which has known problems. The only solution is to either install a different hard disk in the USB enclosure, use a different brand USB enclosure, or install the hard disk inside the computer.)
Solution:
I recommend that everyone who uses ATI set the IRPStackSize parameter in their registry to a value of 20 (hex) or 32 (decimal). If that doesn't work then it won't hurt to try the max value IRPStackSize of 32 (hex) or 50 (decimal). This will assure that your computer will have enough I/O request packet stack space available for ATI and all anti-virus and anti-malware programs plus any other programs which hook into I/O within the OS at a very low level. See the following Microsoft article about how to change the IRPStackSize value and for which OSs that this parameter applies to:
http://support.microsoft.com/kb/285089
Note that if the IRPStackSize does not exist, then you will have to create this new DWORD value and that the value name of "IRPStackSize" is case sensitive. Thus the name must be typed in exactly as shown (without quotes).
You are welcome! I assume that this worked?
Update. See my edited initial post, above, for my new recommended settings for IRPStackSize. Also see this article if event 2011 is showing up in the windows Event Viewer:

Hello GoneToPlaid and oracledba,
Let me clarify some points here.
Yes, that's the correct solution for the cases when computers are not visible from the network after installation of our product. We have the special article (which actually transfers you to Microsoft KB) regarding this issue.
GoneToPlaid, I have also found the thread where you explained a solution on how to prevent PC boos issue after failed installation of Acronis, thank you for that!
I'd like to make sure all your queries regarding Acronis products are resolved.
Additionally to this, you are welcome to ask me any other questions concerning Acronis, and I will assist you further.
Thank you.
I also ran into this issue after installing TI 2009 on a new system running Windows XP Pro with SP3 and all current Windows update (as of 2010-02-11). I was building a new system and started from scratch - no other applications installed. I found that when TI 2009 was installed the Windows Simple Networking stopped working (browsing or mapping a drive) with the "IRPStackSize too small" error. I increased the IRPStackSize to 20, then 32 then 50 with no affect. Un-installing 2009 returned networking.
I have two Win XP systems connected with a cross-over cable running at 1Gb. My TI 2009 system has three HD's and one DVD, the other has one HD and one DVD.
Under these conditions I find that I can not use TI 2009 except from a bootable CD. I was planning on upgrading to the latest release, but now I'm not sure if 2010 is experiencing the same issue. Does Acronis have a solution for this issue? Have they identified the root cause?
