DOCUMENT:Q236355 11-JUN-2002 [sna] TITLE :DLC Link Service Adapter List Empty if 11+ Adapters Configured PRODUCT :Microsoft SNA Server PROD/VER::3.0,3.0 SP1,3.0 SP2,3.0 SP3,3.0 SP4,4.0,4.0 SP1,4.0 SP2 OPER/SYS: KEYWORDS:kbsna400sp3fix kbsna300sp1 kbsna300sp2 kbsna300sp3 kbsna300sp4 sna4 kbsna400sp1 kbsna40 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 3.0 SP4, 4.0, 4.0 SP1, 4.0 SP2 ------------------------------------------------------------------------------- SYMPTOMS ======== If there are more than 11 network adapters configured in Windows NT, with the DLC protocol bound to them, the Adapter dropdown list in the 802.2 DLC Link Service properties within SNA Manager is blank. CAUSE ===== The 802.2 DLC link configuration uses a small buffer size to hold the list of adapter names. The drop-down list is being incorrectly blanked out because there are too many adapter names to fit in the buffer. RESOLUTION ========== To resolve this problem, obtain the latest service pack for SNA Server version 4.0. For additional information, please see the following article in the Microsoft Knowledge Base: Q215838 How to Obtain the Latest SNA Server Version 4.0 Service Pack WORKAROUND ========== In the Control Panel, double-click Network, click the Bindings tab, and unbind the DLC protocol from some of the network adapters until there are 11 or fewer bound with DLC. The remaining network adapters that do have DLC bound to them now appear in the Adapter dropdown list in the 802.2 Link Service properties. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft SNA Server versions 3.0, 3.0Sp1, 3.0SP2, 3.0SP3, 3.0SP4, 4.0, 4.0SP1, and 4.0SP2. This problem was first corrected in SNA Server version 4.0 Service Pack 3. MORE INFORMATION ================ The buffer size has been increased from 256 to 4096 to prevent this problem from occurring.
