Signcode.exe works on one computer but not on another

[Kevin Esler]

I have been beating my head against this problem for several days
now. Any advice would be much appreciated.

In brief: signcode.exe produces a valid downloadable CAB file when run
on one machine, but not when run on a different machine.

I am developing a signed Java applet for use with IE5.5. I use two
computers for development:

- desktop
- laptop

When I sign the CAB file on the desktop machine, it can be
successfully downloaded and executed in my HTML page, but when I sign
the CAB file on the laptop the applet will not load.

Here are all the facts that seem pertinent:

- My desktop machine is running NT4.0(SP4), and my laptop is running
Windows 2000 (SP1), although I use identical copies of
signcode.exe on both machines.

- The invokation of signcode.exe look like this:
signcode.exe -t "http://timestamp.verisign.com/scripts/timstamp.dll" \
-j javasign.dll \
-jp Low \
-spc Rational.spc \
-v Rational.pvk \
ccwebcl.cab

- On both machines I found that it is necessary to run this command
TWICE to get it to succeed. The first invokation fails with:
"Error: Signing Failed. Result = 8007000b, (-2147024885)"
The second succeeds with:
"Succeeded"
I invoke the tool twice in succession in a build-script in a
Makefile.

- Identical .class files are packed into the CAB (I copied them from
one machine to the other to make sure; I also tried recompiling
all Java code on both machines, to no avail).

- The output CAB file from signing is the same size on both
machines, although the contents appear to differ slightly. I don't
know enough about the internal structure to understand where they
differ.

- Both machines are connected to the Internet when signcode.exe is
invoked.

- Other colleagues don't appear to be having the same problem and
are able to sign and then download the CAB file successfully.

- The code download error log produced by IE when the CAB file
signed on my laptop fails to load contains the following, which
doesn't convey much to me:

I founded the problem for this issue.

It appears to be related with having the cab file to be signed in a
mapped drive.

Try copying it to a local drive, an try the signcode again.
