SYMPTOMS
Consider the following scenario:
 * You are using a computer that is running Microsoft Windows XP with Service Pack 1 (SP1) or Microsoft Windows XP with Service Pack 2 (SP2).
 * You have installed security update 821557 (MS03-027) on the computer.
 * You are using the network shortcuts in My Network Places to access the network folder shortcuts on a remote computer.

In this scenario, the shortcuts may generate lots of network traffic. Additionally, the Explorer.exe process that corresponds to this action may stop responding.

<div class="cause_section">

CAUSE
This problem occurs because the network shortcuts (shell links) verify target names every time that the network shortcuts are resolved. A network shortcut is resolved whenever a pointer to an item identifier list that contains one of the target folder shortcuts is bound to the original network shortcut. Network traffic increases because the bind operations take lots of time.

Note Security update 821557 is included in update rollup 826939 for Windows XP. You cannot remove security update 821557 if update rollup 826939 is installed on the computer.
