Howdy and welcome to G2G:

As per Microsoft..

To resolve this issue, use Recovery Console to replace the Isapnp.sys file.

To replace the Isapnp.sys file in Windows XP, follow these steps:

1. Start the computer from the Windows XP CD-ROM.

2. At the Welcome to Setup screen, press R to repair, and then press C to start Recovery Console.

3. At the C:\Windows prompt, type the following command, and then press ENTER:

ren c:windows\system32\drivers\isapnp.sys isapnp.old

4. At the C:\Windows prompt, type the following command, and then press ENTER:

expand cd-romdrive:\i386\isapnp.sy_ c:\windows\system32\drivers\isapnp.sys

For example, type:
expand d:\i386\isapnp.sy_ c:\windows\system32\drivers

5. After the file is successfully expanded, type exit, and then press ENTER to exit Recovery Console.

6. Restart the computer.

says the system cannot find the file or directory specified

[Murray S.]

says the system cannot find the file or directory specified

When does it say that and what did you do just before you got the message??

Murray

[matt13]

i typed it in the recovery console at the c:prompt

[Murray S.]

i typed it in the recovery console at the c:prompt

What did you type in there - exactly???

Murray

[matt13]

ren c:\windows\system32\drivers\isapnp.sys isapnp.old
expand d:\i386\i386\isapnp.sy_c:\windows\system32\drivers
enter after each command

[Murray S.]

Is d: your cd-rom drive letter??

Are you putting a space between the sy_ and c: ??

Murray

[matt13]

yes the drive is d did not put the space in the first time when i did it said unable to create file isapnp

[Murray S.]

You are using a plain old original WinXP install cd and not one of those Recovery/Restore cd's right??

Murray

[matt13]

im using the reinstallation disk cd that cam ewith my computer

[Murray S.]

That's what I figured.. What is the make and model of your system??

Murray

[matt13]

dell dimension 4500

[Murray S.]

It should find it as Dell disks are really just XP cd's with a little extra thrown in..

Have you checked with Dell about the error or their faq's ??

I also encountered this problem in which I was unable to rename the isapnp.sys file on my C Drive. Then I couldn't replace it with a new file off my Windows XP installation CD either. I was finally able to fix the trouble by simply performing the following procedure:

At the C:\Windows prompt type the following command and press Enter

chkdsk /p /r

Note that there are spaces between chkdsk, /p, and /r. Allow this process to run through to completion. Once the program completes, type Exit to reboot Windows. If everything goes right, this may very well resolve your problem.
