Freezing remote screen, must be rebooted to reconnect

Running Version 10, company licensed.  I connect fine to all PCs but have trouble with connecting to my mac.  I tend to get kicked out multiple times a day without warning.  Sometimes I am able to reconnect without issue.  At least once a day I am kicked out and when I try to reconnect it will say "connecting" but nothing ever happens.  I have tried everthing to get it to let me reconnect.  Restarting the program, the local computer, disconnecting and trying again, but nothing works.  I have to have someone reboot the remote computer for me to be able to reconnect.  PCs never kick me out or give me trouble connecting to them.  I have checked all settings for the computer sleep/screen saver and have set them as long as possible or disabled them.
