SYMPTOMS
In SNA Server Manager, the 802.2 DLC tab of the DLC Connection Properties dialog box reports incorrect values for T1 and Ti timer ticks. The drop-down list box should report the following:
Ticks T1 T2 Ti
------------------------------
1 200 ms 40 ms 1 s
2 400 ms 80 ms 2 s
3 600 ms 120 ms 3 s
4 800 ms 160 ms 4 s
5 1 s 200 ms 5 s
6 1 s 400 ms 5 s
7 2 s 800 ms 10 s
8 3 s 1200 ms 15 s
9 4 s 1600 ms 20 s
10 5 s 2000 ms 25 s
Instead of that, the following is reported:
Ticks T1 T2 Ti
------------------------------
1 200 ms 40 ms 1 s
2 400 ms 80 ms 2 s
3 600 ms 120 ms 3 s
4 800 ms 160 ms 4 s
5 1 s 200 ms 5 s
6 2 s 400 ms 10 s
7 3 s 800 ms 15 s
8 4 s 1200 ms 20 s
9 5 s 1600 ms 25 s
0 2000 ms 30 s
If an SNA Server administrator wanted to set the T1 timer to 5s, he or she would select 9 ticks. This will be interpreted as 4s by the DLC layer, which is not the administrator's expectation. Also, for T2 and Ti, the Ticks value 10 appears as 0; the leading digit (1) is truncated.
CAUSE
This was due to a mismatch on the table where timer tick values were associated with a text string indicating the corresponding amount of time.
WORKAROUND
To work around this problem, do one of the following:
- Use the Snacfg.exe command line tool
-OR-
- Set (tick + 1) for T1 and Ti ticks greater than 5 when using SNA Explorer.
STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
With the fix applied, the table is updated so the text strings now indicate the real amount of time for each of the 10 T1, T2, and Ti timer Ticks, as shown on the first table above.
