Problems with mex file, matlab r2009a

Hi,
I am running a .mod file that works well in my laptop, but it does not work in the compute lab (my students need to run it) that has the same version of matlab, but windows xp in a novel network. Using a program to find dependencies, I found out that there is some .dll files missing. The error is:

dynare exerc5v2.mod

Configuring Dynare …
[mex] Generalized QZ.
[mex] Sylvester equation solution.
[mex] Kronecker products.
[mex] Sparse kronecker products.
[mex] Bytecode evaluation.
