My client AXIS C++ in Windows XP is fast but WinNT is slow

[leonardo rodrigo]

Dear all

I have a Axis Client C++ 1.5 with Windows XP and the Web Services is in 
Windows NT and working very good, the Client C is ver fast.
Now,I move the Axis Client C++ to a computer with Windows NT then the client 
is slow. The first query is quick but the second  delay  20 seconds.

Any idea is well received

Best Regard
