Welcome to WebmasterWorld Guest from 188.8.131.52
We previously changed the admin and dns to what we need, ie that of the client.
This time company x have set up a transfer window of 5 days, outwith which you cannot transfer the domain. Is this common? I am no expert but I have not come across this before.
Our client is a pain in the ass as he keeps being slow to forward the transfer the email to us so we can action it. This has cost us a bit of money already and we have signed contracts regarding fees etc.
The five day window is to allow the various contacts to deny the transfer if necessary - if they don't deny it within the five day window, you then have a period of x number of days in which to initiate an intra-registrar transfer.
Remember that you'll only have ten days from receipt of this mail to get the transfer well underway though!
