Modem not conecting

[Jon Sharrock]

Hi.
I have 1 XP Pro workstation with an external modem accepting incoming calls
from 15 remote laptops for file sharing etc.
Two of the laptops both running XP home can not connect.
The other 13 are a mixture of 98, XP home and XP pro and are all fine.
The 2 that do not connect dial go through the screeching modem noise for
about 60 seconds then disconnect with the message "the computer you are
dialling is not responding".
I have tried using the internal modem a USB modem and an external serial
modem on both of these laptops to no avail they all act the same.
The XP Pro workstation has had a new external modem same result.
But with this answering to 13 of the 15 I can only assume it is the 2
laptops not the workstation.
All updates and service packs are done.
Any ideas.
Thanks.
Jon.
