I can fix this issue. Ihese are the steps I have done in the past with RES5.x running Windows 7 32bit.
Go to services and find MICROS Autosequence Server select properties/Recovery
next for 1st failure, 2nd failure & Subsequent Failure select Restart the Service. Next go to Task Manager and select processes. Check the box Show processes from all users. Look for Report Exporter and end process. Also, go to the windows host and make sure it has the correct name and IP's as the back office and workstations. Remove any computer names and IP's not in your db. This is located windows/System32/Drivers/Etc/Host. If site is using 2 NIC cards make sure the MICROS one is listed first. This location is: Control Panel/Network & Sharing Center/ Next select on left side Change adapter settings. Select ALT on keyboard so Menu bar shows. select Advanced tab the Advanced settings. Make sure that MICROS is the 1st listed under connections. This can also be caused by a bad report. If a bad report is run it will lock up all reports from running on Back Office and Workstations. Let me know if that works! I have some more fixes!
Good Luck! Have a wonderful Day!
