PDC/BDC problem

Hi all,

we have a PDC running W2003 Server Enterprise Edition and a BDC running W2003 Server Standard Edition. From time to time, PDC stops working and no one can log to the network, so BDC isn’t working properly. I’ve checked PDC properties and the Global Catalog is checked, but the Global Catalog isn’t checked on BDC. Do you think that could be the problem??.

Thanks in advances.

Alex.
