After you install Microsoft Windows 2000 Service Pack 4 (SP4), or you apply any Microsoft COM+ Rollup Hotfix that is later than COM+Rollup Hotfix Package 20, you may notice many TCP/IP connections to port 135.
A change in DCOM that was first made in COM+ Rollup Hotfix Package 21 causes a part of DCOM to use the Negotiate security package instead of the NTLM security package. The Negotiate package does not have correct credential pooling logic, forcing DCOM to create many connections in some situations.
