Citect SCADA Deployment

Hi, I've been on a site commissioning a project and whenever I attempt to Log In to the Deployment Server in Citect Studio it can take a long time and more recently it has been timing out. In some instances I've had to restart the Server that Citect SCADA is on to log in to the Deployment Server to Deploy my updated Project. Can anyone advise how I can troubleshoot this issue to fix what may be causing it. Many thanks, Gavin
